I'm not familiar with the details, so I don't know the specifics. There's no instruction manual, and I'm not sure if all the parts are included. Due to the age of the product, there may be stickiness, warped parts, discoloration, stains, etc. I intend to pack the item carefully, but if any damage occurs during shipping, please repair it yourself. Please purchase with the understanding and acceptance of a used item. Compact delivery service.
