Purchased new in June 2025. No pets, no smokers. Usage Period: 7 days (The 3 triangular pieces in photos 16-20, 1 long side piece, and 1 short side piece were used for 2 months) Retail Price: Approximately 25,000 yen Items for Sale: Joint mats (70 triangular pieces) Side pieces (short, 31 pieces) Side pieces (long, 16 pieces) Reason for Selling: Since they were hardly used, the condition is quite good. I started using them partially to fill gaps in the room and see how it went, but my child developed a habit of removing the puzzle mats. After using them for 2 months, it became difficult to clean up, so I'm selling them. Important Notes: ▪︎ During the above process, I spilled tea, and although I washed it, it didn't all come out. (I don't think there's any odor.) I've disposed of the mats that didn't come clean, so the number of pieces is less than when purchased. (See details below) I'm selling the areas that were less affected, but there are stains. (Photos) ▪︎ The back of the mats has adhesive, which is normal. Also, the color of the back of some mats is slightly different, but this is part of the original specifications and doesn't affect the adhesion. ▪︎ I chose the gray color, so please confirm that it's not the pattern design like the site below. ▪︎ I'm not currently considering lowering the price. I've tried to check carefully, but I'm a novice, so I may have missed something. ▪︎ I've kept them in a closet, but since it's amateur storage, please refrain from purchasing if you are concerned about minor details. Also, please understand that these are used items. The following is an excerpt from the site: (※ The number of pieces differs as described above. Also, the side pieces are different because I originally bought a campaign item with double the number.) Different Cushioning!
