Please read my self-introduction profile, if you don't mind. As usual, my wife bought a set of two at Costco and just left them haphazardly in the cupboard. It's a ThermoFlask stainless steel insulated water bottle, 750ml. I've only used it three times, filling it with Kurikura water at work to pour coffee for customers, so I haven't put my mouth on it. It looks clean to the eye, but please refrain from purchasing if you are overly concerned about cleanliness. I will ship via Yu-Packet 60 size. Thank you very much. #ThermoFlask
