GECKO BLOCKS™, by Cassidy Labs®

Introducing Gecko Blocks™, a brand new construction toy made of colorful foam blocks that magically cling to each other!

These lightweight foam blocks are coated with a unique, non-toxic, silicone adhesive. They’ll stick to each other, or to glass, and they work great on the shower wall or in the bath tub!

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.

Perfect for young builders.

Recommended for ages 18 months and older
