This is Kumon's Tangram. It's a junior version made only of triangles. It starts with very simple shapes and gradually increases in difficulty, making it a good introduction to learning about shapes. It's not unused, but it's not very damaged and should be usable without any problems. Contents: 24 guide boards 8 wooden pieces The pieces are right-angled isosceles triangles, made of wood, and are about 5cm long and 1.2cm thick. Please check the images for other sizes and contents. Condition: ●●There is no instruction manual. (Actually, this would have advice and example problems...) ●●Also, the boards show some signs of use. Please check the images. (There are no answers, but since it's the junior version, it shouldn't be too difficult.) All pieces are present. Shipping: ●●Since you can still do Tangrams normally with just the cards and pieces, I plan to waterproof and secure the contents only and ship them in a Yu-Packet Post box to offer a more affordable price. Shipping in the original box is also possible if you add shipping costs (about 550 yen). ●I am also selling the standard version of the same series. I also accept combined purchases with other products. (Please forgive me if they are sold out.) Tangrams can be made by cutting cardboard, but having solid shapes and illustrations will likely motivate children and make it easier for them to visualize the shapes. Once they get used to it, they might enjoy creating various shapes on their own. Thank you for looking.
