This is a set of 14 large-size, 20mm thick, wood-grain oak-patterned joint mats. The photos show the mats currently in use, and the color and level of soiling are about the same, so please take a look. - Type: Joint Mat - Thickness: 20mm (size 59cm x 59cm) - Features: Resilience, soundproofing, heat retention, durability Thank you for viewing. I purchased these in 2022 and used them in my living room. There are a few scratches, dents, and some side pieces have been cut, but if you don't mind, they are still in usable condition. They are thick and have good cushioning, so I was comfortable even in winter without a rug, and didn't feel the coldness of the floor. I have them covering almost the entire living room, but I removed some from areas where they weren't needed, so not all the edges have side pieces attached. The 14 mats are probably enough to cover about 3 tatami mats (approx. 3.3 square meters). I will wipe the backs before shipping, but there may be some dirt, so please purchase if you understand that these are used items. No claims or returns accepted. Shipping will be in simple packaging.
