Thank you for viewing. (Please be sure to read the profile.) This is a new, unused mahjong mat that I found while organizing my belongings. It has creases from being stored for a long time, so please stretch it out before using it. Although it is new and unused, the storage period is unknown, and there is some discoloration on the back, but I don't think it will affect its use. Please refrain from purchasing if you are nervous or looking for a perfect product, as this is a long-term storage item. If you are interested in and understand this kind of product, please consider it. I may not be able to reply to comments, so please check the images and make your own judgment. For product protection, the mat will be wrapped in bubble wrap and placed in its original box, which may be crushed. I plan to use Rakuraku Mercari Delivery, size 100.
