Thank you for viewing. Tansu no Gen 【Easy to Care For】 Dining Mat Transparent 150 x 190cm Thickness 1.5mm 【Measures Against Sick House Syndrome】 Clear Mat Waterproof Antibacterial Anti-Mold Floor Heating Compatible Table Mat I purchased this from Amazon, thinking it would protect the floorboards under my family's work desk. However, it wasn't suitable for solid wood, so I couldn't use it. I wanted to return it, but the shipping cost would have been more than the product itself, so I'm reluctantly putting it up for sale. I purchased it in August of this year. Thank you.
