This is a waterproof box sheet. It's a wide king size (for 3 people), 200cm x 200cm x 40cm, and the color is brown. I purchased it in December 2024 and used it for about two months, but I had to buy a new mattress and couldn't use it anymore, so I'm selling it. Although I used it, I always used a mattress pad on top of the sheet (see photo), so it was never used directly against the skin. Because of this, I washed the mattress pad frequently, but I only washed the sheet about 3 times (no dryer) in those two months, and it's in a clean condition without any stains or dirt. It's non-pile, has a smooth feel, and I really liked it.
