Large-capacity mother's backpack. I purchased a new, authentic one on Rakuten and used it for about a year and a half. Since I mostly traveled by car, I didn't use it by carrying it on my back, but rather just used it to put my belongings in... It's quite sturdy and I think it's almost like new. The seams of the water-repellent pocket have become slightly enlarged because I kept a long wallet in it (see photos). The part that hooks onto the hook is creased (see photos). *Will be folded for packaging. Please refrain from purchasing if you are concerned about creases. Features: *USB port (battery not included) *Ponbaby logo is a reflector, so it's safe at night. *Smooth zippers for easy opening and closing. *Two insulated pockets for baby bottles (up to 6 cm in diameter, up to 17 cm long). *Back pocket for storing valuables. *Inside has a water-repellent pocket, so you can put wet items in it. *Water-repellent material that is resistant to water and dirt. *Shoulder straps and back are made of cushioning material to reduce shoulder strain. It is said to be 1.5 times the usual amount. *Strap for attaching to a stroller. *One-touch buckle Allows you to put on and take off the backpack even while wearing a baby carrier. *Stretchable key chain. Height 41 cm x Width 25 cm (excluding pockets) x Depth 6 cm (measured approximately, so there may be some error, but for reference). I think it's clean, but it's a used item, so thank you for your understanding.
