THERMOS water bottle with a double-wall construction for excellent heat and cold retention. - Brand: THERMOS - Model Name: ULTIMATE INSULATION - Color: Beige - Included: Cap, drinking spout - Features: Double-wall construction for heat and cold retention - Size: Approximately 500ml Thank you for viewing. I purchased this about a year ago for around 5000 yen, but I no longer need it as I stopped going outdoors in the cold season. The rubber on the bottom is partially peeling off. There are also small scratches, but it is still usable. I only put hot water in it, so I don't think there is any dirt or odor inside.
