Now that the decorations are in place, let the festivities begin. Your bestie can say cheers to 21 years in any shape or size cup their heart desires! Let them sip their first legal drink out of a 21st birthday martini glass, yard glass, goblet, or even a 21st birthday shot glass necklace. The matching plates and napkins are printed with a burst of colorful confetti and streamer detailing.
