WAQ Titanium Single Mug 450ml WAQ-TM1 This is a titanium single mug I purchased a few years ago from the official WAQ shop on Rakuten. I've only used it once. I will also include the black mesh storage bag that came with the titanium mug. The lid knob and handle move without any problems, but there are some minor scratches and water marks in various places, so please check the images and only purchase if you are okay with them.
