Fine wooden shape sorter box with twisting lock door and screw detachable rotating wheel sorter. 10 pieces of wooden blocks in 5 shapes and colours.It is much more fun than just a conventional wooden shape sorter. Apart from normal shape sorting without the rotating wheel, children can screw on and off the rotating wheel or just spinning it for fun; twist and turn the lock for opening and closing the door.For shape sorting: all the shape slots in one end makes easier for children to compare the different shapes. Children can remove the rotating wheel first as a normal sorting box. For more challenges, attach the rotating wheel on the top, put the right shape block in the appropriate hole then rotate the wheel around until it drops into the correct hole of the box.This wooden sorting toy is suitable for 3 years plus.
