Beige single-size polyester 100%敷きパッド (sleeping pad), machine washable. - Color: Beige - Material: 100% Polyester - Size: Single - Year of manufacture: 2018 - Washing instructions: Machine washable (up to 100°C) Thank you for viewing. I'm selling this because I've used it a few times, but it's just been sitting in the closet, which is a waste. It warms up properly, and its functionality has been confirmed.
