Thank you for viewing! ^ ^ This is the KUMON Communication Toy, "Study Go." It has only been used a few times. There are no missing pieces for either the go stones or the pins. As shown in the 8th photo, one orange pin is broken. It can still be inserted into the board, but it is shorter than the other pins. Also, there are some folds and scratches on the box from storage. Therefore, I have marked it as "Slightly scratched or dirty." Otherwise, there are no noticeable scratches or stains. Please check the photos. For those who understand the aging and home storage, and for those who need it, thank you! ^ ^ - Brand: KUMON - Item Name: Study Go - Number of Players: 2 - Set Contents: Board, stones (green/orange), instruction manual
