Works Alright

These are fun to play with and my (<2) daughter loves them. Easy use and learn, but they pick up dog hair on other things rather quickly and lose stickiness. They work in the bath okay. Water does clean them. Recommend playing on clean surfaces.More > < Less

These blocks stick to stuff like a Gecko.

About Gecko Blocks by Cassidy Labs

Adhere Anywhere

These sticky building blocks are made of nontoxic foam that will adhere together or to surfaces. Kids will have a whole new way to create and play—they can easily build up, sideways, or on the wall.

A silicone finish is what gives Gecko Blocks their stick. And it’s what makes them washable and bathtub-friendly. If they get dirty, or start to lose their “stick,” just rinse them off and they’re as good (and sticky) as new.

Co-Founders Scotty and Mike share a passion for discovery, and believe that learning never stops. Their blocks are a fun, and purposeful, twist on beginner blocks. The stickiness is especially handy for little learners just figuring out this building business.

But even in The Grommet family, we had kids up to 8 years old playing with Gecko Blocks. It’s a new take on a classic toy that a whole range of kids will want to stick with.
