Thank you for viewing. This is a thermos that I have stored at home. I believe it has been used a few times, but there are some rusty spots on the outside due to aging. See images 8-10. Also, I have not confirmed the heat retention ability. For those who like old items, how about it? It seems to be a gift, and the name of the person who gave it to me is written on it, so I have blurred it out. Image 7. Capacity: 1.0L Height: 26 cm Dia Magic Bottle Industry It will be delivered via Mercari delivery, and I plan to ship it with the outer box. Thank you.
