Koguma-kai Wooden Basic Shape Puzzle Set of 3-piece, 4-piece, and 5-piece full sets Includes wooden frames and instructions. Handmade shape magnets included. I handled them with care, but there may be minor scratches or marks. There are two types of wooden frames for squares. (One has a frequently appearing problem from elementary school entrance exam geometry written on it, so please check the image) I personally think the condition is good, but please consider it as a used item that children have used. Because it's made of wood, it looks great displayed in a room and adds a nice atmosphere. Also, it has more weight than plastic, making it easier for children to handle. The large pieces are heavy, and the small pieces are light, which leads to an intuitive understanding of shapes. It's a highly recommended teaching tool because you can learn shapes using your hands and mind. The handmade magnets were created focusing on frequently appearing and easily mistaken problems from elementary school entrance exam geometry. I hope they are helpful.
