This is a stainless steel soup cup made by DOSHISHA. The double-walled stainless steel construction creates a vacuum inside. Because heat is difficult to transfer to the outside, it keeps hot and cold items at their ideal temperature for a long time. The capacity is 350ml. It seems it was also introduced on TV as a "container that doesn't melt ice cream." - Although unused, it has been stored, so there are scratches, stains, and discoloration on the outer box. - The main body appears slightly dull, so please wash it thoroughly before use. - There may be scratches and stains that are not fully captured in the photos. - No claims or returns accepted. - It will be shipped with simple packaging in the outer box. Please consider purchasing only if you understand the above. Thank you for viewing.
