Thank you for viewing. This is the Kumori Waterproof Box Sheet (Single Size, 100 x 200cm / Dark Gray). This is a waterproof box sheet with a TPU waterproof material on the back. It prevents moisture from penetrating your mattress or futon, making it ideal for bedwetting, pet accidents, and use in nursing care. Recommended for those who want to keep their bedding clean. The surface is made of peach skin processed polyester fabric, providing a smooth and gentle touch. The washed finish gives it a natural wrinkle and softness, making it comfortable to use throughout the year, regardless of the season. It also has antibacterial and deodorizing properties, as well as dust mite protection, and is designed with sensitive skin in mind. This "3-in-1" type combines a waterproof sheet, a fitted sheet, and a box sheet, with a moderate amount of padding. It offers a fluffy and comfortable sleep, with more cushioning than a typical box sheet. The all-around elastic allows for easy installation by simply covering your mattress. It fits mattresses and futons up to 30cm thick and is designed to stay in place, even for those who move around a lot in their sleep. 【Size】Single, 100 x 200cm 【Color】Dark Gray 【Material】Surface: 100% Polyester / Back: Polyurethane (TPU Waterproof) This is a new, unopened item.
