Retail price: 3980 yen Approximately 5cm thick, adjustable shell-patterned folding mattress. It was pushed in, so there's a dent in one part. It might return to its original shape if left alone. There's a stain? Or a stain-like pattern. I usually slept with a cover on it. Shipping is 1200 yen, so the price is set a bit high. - Model Name: N Cool SP Shell Pattern NC4 - Thickness: Approximately 5cm - Folding Function: 4-fold - Design: Shell pattern (seashell) Thank you for viewing.
