"This is a new hospital sheet finished with non-woven fabric and thread" (from the description). "It is breathable and highly absorbent, so you don't have to worry about stuffiness from sweat, and it is also strong and won't tear easily" (same). "An average person can use it for 10 days, and it's fine as long as it doesn't tear" (same). It has a soft texture, like a cross between paper and cloth, and it's priced so that you can simply discard it if it gets wet. As it is a product for hospitals, it is suitable not only for those who are providing care but also for those who are anxious during sleep. Some items have been transferred to other bags due to soiled outer packaging, so please be aware of this.
