I purchased these on Amazon for ¥7,238, but they didn't match the room's atmosphere, so I'm selling them. I've removed the backing from a few tiles and temporarily placed them in the room, so those are not included in the count. Below is the product description from Amazon: Brand: by Amazon Target Animals: Dogs Country of Origin: Japan Rating: 4.2 out of 5 stars (430 reviews) 4.2 out of 5 stars Amazon Best Sellers Rank: #1,023 in Pet Supplies (See Top 100 in Pet Supplies) #21 in Cat Towers, Beds & Mats ASIN: B0BTNVJ32X Product Type: Joint Mat Included Components: None Product Height: 30 cm Manufacturer: Sanko Unit Count: 36 pieces Warranty: None Product Description: by Amazon original color, absorbent, water-repellent tile mat for 2 tatami mats (36 pieces). The size is a joint-type mat, 30 x 30cm per piece. The back is absorbent, so it can be easily installed and removed. You can freely combine them to fit your space. They can be easily cut with scissors, so you can lay them throughout your room. There's no need to worry about fraying even if you cut them. Ammonia odor-eliminating treatment reduces unpleasant odors. Suitable for all seasons and compatible with floor heating. They won't be sucked up by the vacuum cleaner, making cleaning easier. At 4mm thick, they are less likely to cause tripping and won't interfere with door opening and closing. Each piece can be machine washed, is barrier-free, thin, and dries easily. (Use a laundry net) How to Use: 1) Remove the film from the back. 2) Determine the placement and start from the edge of the mat. 3) Slowly lower it to the floor and stroke it a few times.
