This is an MSR fuel bottle. 22 fl. oz. / 650ml It's a 25th-anniversary model from 2013. There are scratches, and there's a dent that can be identified when held up to the light. (I will upload images later) It has been used once or twice. This is a vintage item purchased over 20 years ago. I am looking forward to your purchase if you understand that it is old. Please refrain from purchasing if you are concerned about minor details.
