Thank you for viewing this item. I was using this until about 1-2 months ago, but I'm selling it because I bought a new one. I've used it for about 5-10 years, so there are some dents and peeling of the plating, and there is also dirt on the inside of the main body, the lid, and the packing (I think you can see it to some extent in the photos). I was able to use it without any leaks, especially when the lid was closed, so I think it can fulfill the minimum role as a water bottle. However, please note that it is not a product of a major manufacturer, so you can't expect much in terms of heat retention or cold retention. If you have any problems after receiving the item, please contact me before leaving a review. If you have any questions, please feel free to comment. Instant purchase without comment is also welcome. Thank you for your consideration!
