[About the product] After purchasing new, (Purchased on 8/5, received on 8/12) Inflated with an air pump on 8/15 and set up indoors for 5 days. The room has 24-hour air conditioning. I think I sat on it for less than an hour. There is no noticeable damage. I am selling it because the height doesn't match the desk I use. No smokers, no pets. The outer box was shipped from Amazon with the shipping label directly attached, so there are some scratches and damage. However, I will put it back in the same outer box and ship it with a Yamato shipping label directly attached. Anonymous shipping. ★Please refrain from price negotiations m(_ _)m (Please consult if you are purchasing with other items) Although it is a beautiful item, We are waiting for your purchase if you understand that it is a used item.
