Nitori Easy-to-Place, Non-Slip Kitchen Floor Mat 45 x Approximately 180 cm Purchased about 3 years ago, opened but not used due to incorrect size, and stored in a dark place. The surface is a vinyl-like material, so you can simply wipe it clean if it gets dirty. It cannot be washed. There are no noticeable stains or scratches, so I think it can still be used. Please purchase only if you understand that this is a home-stored item. Shipped in simple packaging.
