The sortroller consist of two parts: the body of the snail (with wheeled base) and its shell (cylinder shaped). Pull the snail’s body and watch its shell rolling. Take the shell off and use it as a sorter. It has 6 different shapes to shove the wooden shapes through. This helps the child to distinguish between shapes and enhances their dexterity. You might even find the little one using it as a rattle while shaking the shell full of colorful shapes.
