My wife calls me a “Tea Snob” so I try to live up to the moniker. I drink loose leaf tea, and don't like giving it up when I travel. So I have several Tea infusers that I can carry along. This is a travel case for my “Steep and Stir” loose leaf tea Infuser. For those overnight trips, I can load it up in advance and just carry it along with out the bag of tea. The case comes in handy for after i have prepared my tea. I can simply slip the Tea Infuser back into the case so I can clean it out later. No muss no fuss. The two halves simply press fit together. They are tight enough that I have never had to worry about leaking.
