Handmade 350ml bottle cover. Pouch juice can also be used. If you order, it might be a round button. The lining is made of aluminum. See photo 4. Photo 1: 350ml plastic bottle Photo 2: 300ml pouch juice (I don't know if it fits everything) Photos 5 show the plastic bottle and pouch juice inside. It has a tag, so you can attach your own shoulder strap, etc. Handmade shoulder straps are also available. Please consider them together. When not in use, the gusset can be folded for compact storage. See photo 3. 1 piece is 490 yen. Combined shipping discount is 50 yen. The price varies depending on the fabric. This is just a hobby of a housewife, so I'm sorry for those who are particular. Please purchase from a store or a professional.
