I used this for six years with a cover on it. It hasn't lost its shape, and I think the exterior is relatively clean. Please be aware that the inside is dirty. There are ink stains and discoloration on the vinyl parts inside. I believe the original purchase price was around 60,000 yen. I bought it in 2016, used it for six years from 2017, and then stored it in a bag for two years. I will sell it to someone who doesn't mind a used item. Shipping will be in a recycled carton. Thank you very much.
