This is a Zojirushi thermos water bottle. It's new and unused, so it's in very clean condition. ★Full capacity: 0.75L ★Usable capacity: 0.73L Because it's a thermos, the inside is glass. The pastel colors are very cute. It also comes with a removable strap! Although it's new and unused, it has been stored for a long time. Please understand this.
