Each item is either brand new or used once. The net and air pump are unused. ⚠️ There is age-related deterioration. The following conditions are based on a layman's assessment, so please understand the risks associated with used items before considering a purchase. ⚠️ The brand new item has a slight air leak. The film is still attached, so air cannot be pumped in, and it remains in that state. (It is believed that it can be used without issue after opening and inflating.) ⚠️ There is age-related deterioration due to long-term storage (photos 10-12). Even brand new items may show some cracks when inflated. ※ Due to shipping costs, individual sales are not possible, so please understand. ※ These items have been stored at home, so please refrain from purchasing if you are looking for a perfect item.
