Instant purchase is OK. No discounts. ⚠️ This is NOT a "set of 3". This does NOT include an "insulation/refrigeration cover". This is NOT a "500ml water bottle". There seem to be various similar products, so please read the following carefully before considering a purchase. [Vintage Item] "Foldable 1000ml Water Bottle" - Items for sale: 1 - Model Name: Pechanko Water Bottle (Simple Water Bottle) (Includes: 1 water bottle, 1 insulation/refrigeration cover, and 1 plastic funnel. Everything seems to be packaged together.) - Main color of the water bottle: Yellow. Yellow with a camel illustration! - Water bottle capacity: Approximately 1000ml - Features: Foldable and lightweight, useful for outdoor activities, walks, leisure, travel, and emergencies. Freezer-safe! ⚠️ This is an unopened item. However, a considerable amount of time has passed (the design and text feel dated; it's impossible to determine when it was purchased), and we are not responsible for the internal quality. It might be better to consider it as a disposable item for emergencies or as a collector's item. ⚠️ The packaging has some minor dirt and scratches, but it's in good condition for its age. ⚠️ Shipping: Yu-packet Post (delivered to mailbox). It will be shipped in a paper envelope as is. No bubble wrap. No special measures will be taken to prevent folding. Only a "Do Not Bend" sticker will be applied. Please be aware that if your mailbox is narrow, it may occasionally be pushed in. This item belonged to a family member who loves mountain climbing. It seems to have been purchased at a sports specialty store. They bought three, and one was washed and used repeatedly, and it seemed durable. The two new ones were carefully stored in the back of a cupboard (in a place away from sunlight). This is not a 100-yen shop product. It doesn't feel cheap like similar products, and the construction seems solid. It is (probably) no longer in production, so it may be a welcome item for those who use the same product. Please see the photos from the third image onwards for product details. These are not the items for sale, but the first one that has been opened, so please rest assured. ★ There are two in stock ★ A set of two of the same item is 1100 yen (please comment if you wish). However, the condition of both is almost the same, so we cannot add more photos.
