Match your mermaid theme or underwater them to our Prism Bubbles Full-color Key Chain. It's a memorable custom keepsake for Prom, a Homecoming dance, or Winter Formal. The clear acrylic key chain holds one 2 1/2" x 3 1/2" photo on one side and a paper insert with our full-color Prism Bubbles graphic on the other side. Add your choice of text and/or imprint design in one color to personalize the key chain for your school event. Add a custom key chain to swag bags, hand it out at the door of your event, or p8t one at every place setting. Look for our Prom invitations, ticket, and other favors with the same Prism Bubbles graphic to create a coordinated look for Prom.
