Although this product is new and unused, there are some stains that appear to have occurred during manufacturing or storage. 【Five-Sided Complete Waterproof Design! Side Protection Included】 Based on valuable feedback from customers who pointed out that the sides were not waterproofed, we have developed a fully waterproof sheet. This product has evolved from previous models to offer five-sided waterproofing, effectively protecting against spills and stains on futons and mattresses, as well as being suitable for nursing care and bedwetting. The lining uses a waterproof and breathable TPU material, protecting your mattress and futon from moisture and dirt. It reduces discomfort and allows you to spend your time comfortably. 【Absorbent, Quick-Drying, Anti-Dust Mite, and Antibacterial】 The fully waterproof sheet dries faster than previous products after being machine-washed. It prevents dust mites from breeding by not allowing them to accumulate nutrients like care, dust, and moisture on the mattress. You can use it comfortably throughout the year. 【Peach Skin Finish & Reduced Rustling Noise】 The fully waterproof sheet has a peach skin finish, providing a smooth, peach-like texture that resists pilling and wrinkles, and minimizes rustling noise. In addition, it has a 360° anti-slip rubber band around the entire perimeter, making it easy to put on and take off, and it stays in place even if you move around a lot in your sleep. 【Box Type, Machine Washable, Various Uses】 The fully waterproof sheet is a full-coverage box type with a 360° elastic rubber band that completely covers the mattress. It is wrinkle-resistant and easy to remove and wash. It is suitable for most commercially available mattresses. It can be machine-washed at home and used cleanly at any time. Ideal for bedwetting, pets, urine leakage, and hygiene measures. 【Product Specifications】195*195*30cm
