I bought this when I got a cat, but I didn't need it. I washed it at home 2-3 times and disinfected it with bleach (chlorine), then stored it carefully at home. I haven't had a chance to use it, and the condition is good, so it seems a waste to throw it away. I'd like to offer it to someone who needs it. Thank you for your purchase. 【Product Information】 Material: Surface - 100% cotton (terry cloth), Back - Polyurethane waterproof material Care: Machine washable Size: Semi-double 120*200*30CM Color: Waterproof White Design: Straps Price: Purchased on Amazon for around 2,800 yen Condition: The condition is good, with no noticeable stains or scratches, and of course, no odor.
