In addition, it has a 380° all-around anti-slip elastic band, making it easy to put on and take off, and it's fine even if you have a restless sleep. 【Box Type, Washable, Various Usage Measures】The box sheet is a 360° elastic full cover 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 washed in your home washing machine and can be used clean at any time. It is ideal for bedwetting, pets, urine leakage, and hygiene measures.
