This is a Kumon educational toy designed to foster three-dimensional thinking through various experiments. Why not try it with your child? Kumon Publishing Figure Cube Building Blocks WK-32 4A04 Target age: 3 years and up Contents: 24 cards (explanation, problems) 50 wooden cube blocks 2 sticker sheets Size: Box size is approximately 14.5cm square, height approximately 8cm Blocks are approximately 2.5cm cube. ● One card has a crease. Also, one sticker sheet is missing. The stickers have not been applied to the cards. Other than that, although not in the same condition as new, I think it is in relatively good condition. Both the cards and building blocks are complete in number. ● After cushioning and securing the contents inside the wooden box, the outer box will be waterproofed and shipped in a Yu-Packet Plus dedicated box. I thought it was well-designed, and the advice for supporters is also substantial. Thank you for looking.
