Thermos Stainless Steel Bottle Cup Type FFM-502 * Capacity: 500ml * Color: Stone Black Thanks to its vacuum insulation, it has high heat and cold retention. Comes with a cup, convenient for going out. In the coming season, it's a cup type that makes it easy to drink warm beverages. The capacity size is neither too small nor too large, making it the perfect size for carrying around. It has a sleek, straight shape. While this also comes in silver, compared to silver, where surface dulling and dirt from small scratches become noticeable with use, black is less noticeable and can be kept clean for a long time. I've used both silver and black, but black stays cleaner even with long-term use. Recommended.
