I bought these LovesTown 18PCS Sequin Keychain, Mermaid Animal Flip Sequin Keychain Key Chains for Kids Key Chains Backpacks for my 6 year olds dolphin themed birthday party and all the kids (and some adults!) thought they were really fun. We gave them out as party favors. So far quality seems decent: 2 weeks later they're still intact, even with lots of play and being attached to the kid's backpacks. Overall great buy and I highly recommend.
