Fat Brain Toys InnyBin

Fat Brain Toys InnyBin is a tactile shape-sorting adventure that transforms learning into pure discovery. Six uniquely textured shapes—cube, diamond, sphere, triangle, flower, and Fat Brain logo—challenge little hands to push through the cube's elastic bands, sparking curiosity and experimentation at every turn. Perfect for developing fine motor skills and tactile awareness, InnyBin offers a frustration-free approach to shape exploration. Each shape measures approximately 2 x 2 x 2 inches, while the cube itself is 5.5 x 5.5 x 5.5 inches—ideal for curious hands to grip and manipulate. Watch as your child explores, experiments, and discovers through play. It's beautifully simple yet amazingly mind-expanding.
