Beistle
21st Birthday Party Bead Necklaces
from $1.82
Toss one of these bead necklaces over each guest as they arrive and the 21st birthday crowd sorts itself out from everyone else at the venue. At 36 inches, the strand slips on over any outfit with no clasp to fumble.Colors come assorted, so no two people need to match. Sold by the package (1 necklace) or by the case (12 necklaces); the case covers a decent-sized group.
Beistle
21st Birthday Party Centerpiece
from $4.90
Cascading strands give this 21st birthday centerpiece height and movement without a wide footprint, so it registers on a crowded table while leaving room for the food. Setup amounts to placing it, and the durable construction survives being relocated when the pizza shows up.
Colors: blue and gold
Height: 13"
Sold by the package (1 centerpiece) or by the case (12 centerpieces)
Beistle
21st Birthday Party Decision Dice Game
from $2.98
Two dice, one game: the first die assigns a dare, the second decides who does it or where it happens. That is the entire rule set, which is about the right level of complexity for a 21st birthday as the night goes on.The black and white dice work as a shared activity or, bought by the case, as party favors. Sold by the package (1 game) or by the case (12 games).
Beistle
21st Birthday Party Door Cover- Multicolor
from $6.30
Nobody walks past a door that says 21 and wonders what the occasion is. This multicolor cover measures 5' x 30", sized to dress a standard door in a single piece, and the durable plastic holds up through a full night of doorway traffic.
Material: plastic
Suitable for indoor or outdoor use
Sold by the package (1 door cover) or by the case (12 door covers)
Beistle
Glittered Metal 21st Birthday Party Tiara
from $9.80
A silver tiara with a glittered finish for the 21st birthday guest of honor. Two attachable combs anchor it in place, which matters at a party where the wearer is dancing, hugging, and posing for photos all night; the combs do the holding so nobody has to.
Material: metal
Sold by the package (1 tiara) or by the case (6 tiaras)
Beistle
21st Birthday Party Door Cover- Navy and Gold
from $6.30
Navy and gold plastic door cover printed for a 21st birthday, sized 6' x 30" to fit most standard doors. It is made for indoor and outdoor use, so it can go on the front door where arriving guests actually see it instead of inside where decorating budgets usually pool. Plastic also shrugs off weather better than paper ever will.Sold by the package (1 door cover) or by the case (12 door covers).
Beistle
21st Birthday Party Whirls Assorted Colors - Assorted colors
from $6.30
Hanging decorations for a 21st do not need to be complicated. These 3-foot multicolor whirls are lightweight, go up indoors or out, and fill the vertical space that table decorations and wall banners leave empty.Sold by the package (5 whirls) or by the case (30 whirls); the case is enough to cover a full room without rationing.
Beistle
Finally 21 Fringed Tiaras (4-Pack) - Assorted Designs
from $4.90
Four fringed tiaras in assorted designs, packaged together so the guest of honor is not the only one wearing something on her head. Fringe gives it movement that a flat foil crown never has.Because the four designs differ, a group photo ends up with some variety in it instead of four identical crowns in a row. Sold by the package (4 tiaras) or by the case (48 tiaras).
Beistle
Foil Happy Birthday Party Streamer (Navy)
from $7.35
Solid navy with foil on both faces, this Happy Birthday streamer is for parties that skipped the pastel palette. Double-sided foil earns its keep because streamers twist as they hang; whichever side rotates toward the room still shines.
Size: 6" x 10'
Sold by the package (1 streamer) or by the case (12 streamers)
Beistle
21st Birthday Party Cascade Centerpiece
from $7.35
Eighteen inches is tall for a centerpiece, and that is the point: this multicolor 21st birthday cascade reads from across the room, not just from the next seat over. Assembly is easy, so it can go up while the cake is still in the box.Sold by the package (1 centerpiece) or by the case (6 centerpieces); the case makes sense when every table at a bigger party needs one.
Beistle
Happy 21st Birthday Party Sign Banner
from $6.65
Sixty inches wide by 21 inches tall, this Happy 21st Birthday banner comes with 4 grommets, so it hangs flat against a wall or fence instead of curling at the corners. The multicolor print reads clearly from across the room.Sold by the package (1 banner) or by the case (12 banners), which is worth knowing if you decorate a bar or hall regularly.
Beistle
Finally 21 Luncheon Napkins (16-Count) - Two-Ply Paper
from $4.55
Two-ply luncheon napkins in the Finally 21 print, sized for a plate of food rather than a glass. Sixteen per package works out to roughly two apiece for eight guests, which is the ratio to plan on once cake is involved.
Two-ply paper construction
Luncheon size, folded
16 napkins per package, about 8 guests
Coordinates with the Finally 21 plates and tablecover
Sold by the package (16 luncheon napkins) or by the case (192 luncheon napkins).
Beistle
Finally 21 Dinner Plates (8-Count) - 9 Inch 21st Birthday
from $4.55
Nine-inch dinner plates, eight to a package, printed in the Finally 21 design. Nine inches is the diameter that holds a slice of pizza without anyone folding it in half, which matters more at a birthday than the pattern does.Eight plates covers a small table once through the line; for a party where people go back for seconds, count on two per person and buy accordingly. Sold by the package (8 plates) or by the case (96 plates).
Beistle
Finally 21 Dessert Plates (8-Count) - 7 Inch Cake Plates
from $3.50
Seven-inch dessert plates in the Finally 21 print, which is the size that exists specifically for cake and does not encourage anyone to load it with pasta salad.
7 inch round
8 plates per package
Matches the 9 inch Finally 21 dinner plates
Handles cake, ice cream, or a small appetizer round
Sold by the package (8 plates) or by the case (96 plates).
Beistle
Finally 21 Beverage Napkins (16-Count) - Two-Ply Cocktail Size
from $3.50
Beverage napkins are the ones that disappear fastest, because every drink handed across the counter takes one and none of them come back. Sixteen two-ply napkins is a single round for a group of sixteen, so these are worth buying in multiples rather than one at a time.The smaller cocktail fold also slides under a slice of cake when the dessert plates run out. Sold by the package (16 beverage napkins) or by the case (192 beverage napkins).
Beistle
Finally 21 Drink Pouches (6-Count) - Lanyards and Straws
from $9.10
Six 16.9-ounce drink pouches with lanyards already attached and straws included. The lanyard is the practical part: a pouch hanging at chest height leaves both hands free and does not leave a ring on somebody's furniture.Each pouch seals well enough to survive being carried around a yard or a dance floor, and the printed Finally 21 design makes it obvious whose party it is in the photos. Sold by the package (6 drink pouches) or by the case (72 drink pouches).
Beistle
Finally 21 Plastic Tablecover - 54 x 108 Inch Party Table Cover
from $7.00
Fifty-four by 108 inches of plastic, which covers a standard 8-foot banquet table with a few inches of overhang on each side, or a 6-foot table with a proper drape at the ends.Plastic is the right call for a 21st: it wipes down, it does not wick a spilled drink through into the wood underneath, and at the end of the night it goes in the trash instead of the laundry. Sold by the package (1 tablecover) or by the case (12 tablecovers).
Beistle
Gold 21 Cascade Centerpiece - 18 Inch 21st Birthday Table Decor
from $7.35
An 18-inch cascade centerpiece in gold, built to sit at the middle of a round table and be legible from every seat around it. Because it builds upward rather than outward, it takes almost no plate space, which is the usual complaint with centerpieces on a crowded table.Gold holds its color under warm indoor light instead of going muddy, so it still reads in the background of the cake photos. Sold by the package (1 centerpiece) or by the case (6 centerpieces).
Beistle
FunShotz Novelty Shot Cups (4-Count) - 1 Oz Party Shooters
from $5.60
Four one-ounce shot cups, 30 ml apiece, in a novelty shape that gets noticed at the moment it is handed over. Four to a package means they get distributed as a set rather than passed around as a single gag.The case runs 20 packages deep, which is the quantity that makes sense for a bar running theme nights all season rather than one party on one weekend. Sold by the package (4 cups) or by the case (80 cups).
Beistle
Finally 21 Hanging Whirls (12-Count) - 21st Birthday Decor
from $7.70
Twelve hanging whirls running 17.5 to 30.5 inches, split six with printed 21st birthday icons and six plain to break up the pattern. Staggering the lengths reads better than a straight line, and the two styles give an easy way to do that without every strand looking identical.They turn on their own in any moving air, so a doorway or the corner near a ceiling fan is where they earn their keep. Sold by the package (12 whirls) or by the case (72 whirls).
Beistle
Finally 21 Jointed Streamer - 6 Inch x 8 Ft Party Decoration
from $7.35
Six inches tall and eight feet long once assembled, this jointed streamer strings across a doorway, along a mantel, or down the front of a buffet table. Assembly is a few minutes of connecting sections before it goes up.Eight feet spans most interior doorways with enough slack for a slight dip in the middle, which looks better than pulling it drum tight and watching the joints strain. Sold by the package (1 streamer) or by the case (12 streamers).
Beistle
Finally 21 Oversized Sign Banner - All-Weather 30 In x 6 Ft
from $6.13
Thirty inches by six feet of all-weather banner, hung the long way along a fence, a garage door, or a porch railing where a paper sign would not last the afternoon. The oversized format is built to be read from the street rather than across a room.It lies flat against a hard surface or spans between two anchor points, so a driveway announcement takes about a minute to set up. Sold by the package (1 banner) or by the case (12 banners).
Beistle
Finally 21 Photo Fun Signs (9-Count) - Double-Sided Props
from $6.30
Nine photo props ranging from 5 to 18 inches, printed on both sides so nobody picks one up backwards. That detail stops mattering in theory and starts mattering the second a group is passing props down a line.The size spread gives a mix of small handheld pieces and larger signs that stay legible in a wide group shot. Sold by the package (9 signs) or by the case (108 signs).
Beistle
Finally 21 Door Cover - All-Weather 6 Ft x 30 Inch
from $6.30
Six feet by 30 inches lands this cover at the dimensions of a standard front door, and the all-weather construction makes the outside of that door a real option rather than a bet on the forecast.Indoors it does just as well as a wall panel behind a drink table or at the end of a hallway. Tape the top two corners first, then smooth downward, and the print stays flat instead of bubbling. Sold by the package (1 door cover) or by the case (12 door covers).
Beistle
Finally 21 Centerpiece Sticks (8-Count) - Four Designs
from $5.60
Eight centerpiece sticks between 10 and 11 inches, two of each of four designs, printed front and back. Two of each is what keeps a long table looking like a repeating pattern instead of one good stick and seven afterthoughts.They push into a cake, a block of floral foam, or a cup of candy, and the double-sided printing keeps them readable from both sides of the table. Sold by the package (8 centerpieces) or by the case (96 centerpieces).

"In Love with Beistle products! I recently purchased Beistle die-cut products from Bulk Party Supply, and I'm beyond impressed! The shipping was incredibly fast, and the communication throughout the process was top-notch. The quality of the die-cuts is outstanding—the pumpkins were amazing, the cupids looked terrific, and the hearts were perfect. The packaging ensured everything arrived in pristine condition.
