Three out of the four are new. One has been used, so there are stains if you look closely. It's reversible, so you can use it with either the white or silver side. The material is PVC leather specially made for this product by the leading domestic leather manufacturer "SINCOL". It's water-repellent and stain-resistant, and unlike flimsy fabric, it's sturdy and soft, maintaining a like-new texture. I don't remember the exact price, but it was about 1,800 yen per piece. Price is not negotiable.
