Purchased around May 2025 and used for about a month, then stored at home. I washed it frequently with baby detergent (Araubaby), so I think it's in relatively good condition, but if you're concerned, please wash it again after purchase before using. My impression is that it rounded out a little bit more than if I hadn't used anything. After that, I was able to roll over, and I stopped using it in a flash, so I think it's a good idea to get it cheap and try it out (^^) - Brand: SMORbi - Color: White - Design: Checkered pattern - Material: Mesh - Retail price: 3,980 yen Will be shipped in simple packaging.
