This is a THERMOS stainless steel vacuum-insulated bottle. I used this myself, but it's not a direct-drink type, and I didn't use the cup (cap) either. (I used a different cup.) I used it about 10 times, but it was inconvenient for me that it wasn't "direct-drink," so I cleaned and dried it and then stored it. I thought it was a waste to just keep it stored, so I'd like to offer it to someone who needs it. It didn't come with a box when I bought it from the official website. I searched for the product number from my purchase history and gathered information about the product on the official website again. ● THERMOS ROB-002 ● Stainless steel vacuum-insulated construction ● Color: Midnight Blue ● Diameter: Approximately 75mm ● Total height: Approximately 245mm Images 8-10 are for product description and were taken from the THERMOS official website. For this listing, I cleaned it again and performed a hot water sterilization, also as a heat retention test. I haven't used alcohol or disinfectant products, as improper use by an amateur might damage the packing, etc. There is no deterioration or deformation of the spout or the packing of the inner stopper, and there were no leaks even when hot water was poured in. There are some scratches and minor dents from when I dropped it once, but I think it can still be used as a practical item. Please consider purchasing only if you understand that this is a "used item." Also, when sending the product, I will use recycled packaging materials, etc., and I would appreciate your understanding of this cost- and environmentally-conscious approach. (I plan to ship via courier service.) Due to work, it may take some time to contact you or ship the item. If you are in a hurry, please refrain from purchasing. (I will try to respond as quickly as possible.) Thank you very much. 【Note】 Although I have cleaned and sterilized it with hot water, this is a used item being sold by an individual amateur, not a corporation. It goes without saying, but from a hygiene perspective, please be sure to wash it before use.
