I am a fan of Bare Necessities products and have attended their Zero Waste workshop. When I first saw the reusable tumbler, I was overjoyed because I travel frequently and its not easy to avoid "paper" cups, Styrofoam cups etc. Carrying a glass or a bowl was my solution but it added bulk and took space in my bag. So, this tumbler is just the right thing for me. I like steel a lot. I use this tumbler to drink water, beverages and even for Gol Gappas or small snacks that can be fit into it. Another Zero waste product in my kitty and in my journey to a Zero Waster lifestyle thanks to Bare Necessities.
