Oval bed-in-bed mattress made of breathable mesh material, specifically for Neo Mamaiism. I bought it as a spare and washed it, but I only used it once. Retail price is 2,480 yen. It's almost unused and in good condition, but it has been opened and used once. There is no dedicated bag or anything. Please understand this before purchasing. - Color: Gray - Shape: Oval - Material: Mesh Thank you for looking.
