I am a Mate fan so I drink a lot of it, but I also travel al lot. So I designed this compact set to take the Mate without the pain of carring a lot of separate elements.
The amount of yerba you can carry in the main container is enough for 2 preparations (60gr, 30g each). Besides, you can also load the first preparation in the vase, so you can carry 3 preparations each time you go out with this set.
Later, I have realized that this set can be also used for coffee, if you load the main container with soluble coffee (or the mix of your preference) instead of yerba mate.
For the vase and the tube for sipping the wall line count should be 4 or higher and could be a good idea to increase the vase infill.
