For rehearsal dinners, birthdays, and beach house gatherings, color changing mood cups turn cold drinks into a simple color-change surprise in a 16 oz stadium cup. Beginning translucent clear, they shift to a translucent color when ice cold liquid is poured inside, making them suitable for adults and kids alike. They work well for Cinco de Mayo celebrations, bachelorette bashes, cocktails at home, and take-home favors for visitors and friends. Side 2 can be personalized at no additional cost, and custom logos or artwork may also be used when supplied in the proper format for approved custom printing.
