This is a Doctor Mat L size from Asahi Keikinzoku. The first photo is a composite of two images with the mat's orientation changed. I temporarily stopped listing this item because I thought I might use it, but I've decided I won't, so I'm relisting it. I'm offering a discount on this large item for a limited time during the consecutive holidays. Product details are as follows: Size: 183cm x 51cm Thickness: 2cm Color: Rich Brown Construction: 2-layer structure (waterproof on one side) Accessories: Instruction manual 1-month DIARY to create myself (bonus at the time of purchase, unused) Regular price: 14,900 yen (excluding tax) This is a consignment from my mother. She purchased it in November 2024, hoping it would make things easier because the worktop in her kitchen at home is too high. She used it for a few months, but stopped using it because she almost tripped on the edges despite the tapered design. She wiped off the light dirt and put it away. Therefore, although there isn't much sign of use, there are creases from being rolled up and stored, and marks from the plastic ties that held it together. Because it's a flexible material, I think the marks will naturally disappear if you unroll it and leave it for a few days, but please understand that this is a used item before purchasing. Also, height adjustment is only a secondary benefit. The main effect is to reduce the burden on your feet, back, and knees, and it has a proven track record of use in factories, etc. Thank you for your interest.
