Almost final price reduction. I want to get rid of it by putting it out as burnable trash. Amazon.co.jp: Joint Mat Iro-Iro Fit, 1.5 shaku (approx. 1.5 tatami mats), 8mm thick, 12 pieces, Rug/Mat Color: Sunny Side Lemon : DIY & Tools & Garden https://share.google/aGX6pe40ivGVPQ63e I mistakenly purchased this, and it's unopened. When I tried to return it, I received a reply saying, "We will have you transfer the fee." So, I decided to list it here. I'm using the 10mm thick version, which is 2mm thicker. I ordered this as a spare for warping with a hot carpet and made a mistake in ordering it in a hurry for cold weather protection. This is the same product that is No. 1 in popularity for joint mats on Rakuten. I've been using it for 2 years as a kids' room, and I'm very satisfied. It would be useful for preparing a kids' space during maternity leave, filling in small level differences, making handmade toys, covering areas where pets tend to have accidents, and creating a space for baby-led weaning. When I bought it, it was 3333 yen including shipping. I will cover the shipping cost of 1050 yen.
