Waterproof white sheets, made of a polyester and cotton blend, machine washable and dryer safe. - Brand: ANGEL - Material: 65% polyester, 35% cotton (waterproof) - Color: White - Washing Instructions: Machine washable up to 60°C, tumble dry (up to 130°C) Thank you for viewing. This is a set of two. I used these for caring for family members. I purchased them for 3300 yen each. I only used each one for about a week, and I've washed them only once or twice. I thought it would be a waste to throw them away, so I'm listing them for sale. They have wrinkles from being washed and folded, but I don't think there are any noticeable stains. If you don't mind, please consider purchasing them.
