Thank you for viewing. This is the KUMON Shape Cube Building Blocks. The building blocks themselves are in very good condition. There is a chip on the lower left side of the wooden box, but it does not affect the opening and closing of the lid (see photo). There are 17 pattern cards (34 patterns total, front and back), although there are originally 18. It seems that one card has been lost. Thanks to playing with this product a lot, my child has also come to love assembling small LEGOs. Please understand that this is a used item that has been used by a child, and consider purchasing. It is being sold at a low price because it does not have a box. Size: Building blocks W2.5 x H2.5 x D2.5cm 50 building blocks (10 each of red, blue, yellow, green, and orange) Type: Building Blocks Type: Building Blocks
