I planned to use these to prevent pet accidents, but since the accidents have decreased, I'm selling them. One was washed with water but is unused. The other is brand new and unused, never washed. Quoted from the following site: Brand: Vallein Color: Khaki Size: Single Material Composition: 100% Cotton Features: Peach skin finish, Washable, Quick-drying, Antibacterial and Deodorizing, Waterproof Closure Type: Zipper [Product Specifications] Single: 100*200cm Top Fabric: 100% Cotton Towel Fabric, Back Fabric: PE Waterproof Sheet [Notes] Due to shipping costs, we use simple packaging such as compression packing. The initial odor after opening will disappear with use, but if you are concerned, we recommend air drying. [Achieving a Comfortable Sleeping Environment] The top fabric uses towel fabric, which is soft. It allows for smooth turning over and maintains comfortable sleep throughout the night. It uses a skin-friendly material that can be used with peace of mind by those with sensitive skin. The back fabric uses waterproof and breathable TPU material, protecting mattresses and futons from moisture and dirt. It reduces discomfort and allows you to spend your time comfortably. [Absorbent, Quick-drying, Anti-mite, Antibacterial] The use of towel fabric achieves a good sleeping experience. After washing in the washing machine, it dries in a shorter time than conventional products. It prevents the accumulation of care, dust mites, and moisture, which are nutrients for dust mites, on the mattress, thereby suppressing the breeding of dust mites. You can use it comfortably all year round. [All-Season Compatible, with Rubber Bands] Featuring a soft feel, this mattress pad is active all season long, in both the sweaty season and the cold season. With reinforced rubber bands on all four corners, it fits perfectly on beds/mattresses/futons up to 30cm thick! It secures firmly, is easy to put on and take off, and is fine even if you toss and turn. [Washable, Various Use Measures] Useful to have multiple for replacements and for guests. It is wrinkle-resistant and easy to remove and wash. It is suitable for most commercially available mattresses. It can be washed in your home washing machine and can be used clean at any time. Ideal for children's bedwetting, pets, urine leakage, and hygiene measures. We recommend purchasing two or more.
