GelGems® bag (large: squirrely)

I was skeptical at first, but these clings really do stick perfectly to my bathroom mirror without sliding off. The squirrely shapes add a playful touch that my toddler absolutely loves to rearrange. Definitely worth it for the instant window makeover.

I bought these for my car's back window and they actually hold on tight even when it's hot out. The shapes are so squiggly and fun—my toddler squeals every time she spots them.

My daughter loves arranging these on the sliding glass door, and she's already trying to count the different shapes. The gel texture holds up well to her constant repositioning.
