ZOKU Stainless Steel Bottle, 500ml capacity, Mint Green This item has been kept in storage since purchase and has never been used. I use other colors of this bottle, and it's well-made and keeps drinks cold well. The top strap can be removed. Currently priced at 4400 yen on Rakuten Ichiba (as of October 2025). Although unused, please understand that this item has been stored at home, so please purchase only if you are comfortable with this.
