This is an unused Zojirushi water bottle, a brand known for its reliability. I'm selling it because I've kept it in storage without ever using it. I discarded the box after I bought it, and there are some minor scuffs on the edge of the bottom from storage, but they're barely noticeable and not a concern (see images 6 and 7). It has few parts, making it easy to clean. The opening is large, so it's easy to add ice. Model number: SM-JB48AZ-XA
