Thank you for viewing. (Please be sure to read the profile before purchasing) This is a brand new, unused mahjong mat that I found while organizing my belongings. It has been stored for a while, so there are creases and discoloration on the back. The storage period is unknown, so please refrain from purchasing if you are sensitive to these issues or are looking for a perfect product. If you are interested in and understand this type of product, please consider purchasing. I may not be able to reply to comments, so please check the images and make your own judgment. For shipping, I will wrap the mat in bubble wrap and package it in the original, slightly crushed box.
