Cushion floor, wood grain, used I was storing it for audio use, but the environment changed and it was used, but I was only storing it. There are stains, discoloration, dents, etc. Please understand. I'm also cleaning up, so if it doesn't sell after a week, I'll dispose of it! Please use it somewhere you can, such as for soundproofing, sound dampening, sound absorption, children, or pets. There are no edges. There are a mix of those with all the barbs and those with the edges cut straight. There are 15 pieces with all of them, and 7 cut pieces, for a total of 21 pieces. I will also include the cut-offs. I haven't checked the details, so there may be some without unevenness. From the above, there are a number of pieces, but there are also chips, so please consider it as junk. There are also mats without unevenness, so you may need to take measures such as hiding them with carpet. I think it can be used for various purposes, not only for children, but also for pets, for placing under a trampoline, etc. If it doesn't sell for a while, I will dispose of it. Thank you.
