Thermos Mountain Bottle. FFX-500(BK) There are scratches on the bottom, but there are no problems with heat retention. Please check the condition of the exterior scratches in the photos. Weighing 270g, it's a lightweight water bottle with an excellent balance of lightness and heat retention. There are no leaks from the packing at the moment. I've only used it for hot water, so I don't think there's any odor. #Thermos #MountainBottle
