This sort-roller consists of two parts; the body of the snail (wheeled base) and its shell (cylinder shape). Once you pull the snail body, you can watch its shell magically roll round. It contains six-block shapes that can be taken out and removed from the shell. The shell has six different shaped holes that work great as a puzzle. This helps any child to distinguish the difference between shapes and it enhances their dexterity. Made for ages 1+ years and up. Size: 8.6" x 6.3" x 7.25".
