This is a KOBUN arithmetic set. It was purchased new and used by two children. I am selling it because it is no longer needed. Contents: - Counting chips (includes one die) - Blocks - Clock - Shapes (building blocks, color plates) - Counting sticks - Practice board - Sheet set - Instruction manual The "number cards" and "calculation cards" are only the cases. The contents are omitted because they are heavily damaged from use. Please purchase them separately if needed. Name stickers have been removed. The writing on the box has also been erased. The contents of the sheet set have been directly labeled, so a tack sticker has been applied over them. Also, some of the sheet set bags and paper items have direct markings that remain. The paper ruler has creases, stains, and marks from circles and numbers written on it. (These have been erased as much as possible) The plastic items have been wiped with alcohol wipes. There are some stains and scratches from normal use, but I think it has been used cleanly. Please understand that this is a used item before purchasing. For the purpose of decluttering, I will not sell items separately. I am not currently considering lowering the price. Thank you for your understanding.
