Y thinkgeek ya los esta supliendo, "Yerba Mate and Bombilla Set" en Thinkgeek
Yerba Mate is a delicious drink which has some magical properties. You see, inside each sip are mystical alkaloids in the same family as caffeine and theobromine - alkaloids that give you a bigger boost than their cousins, while being more gentle on your stomach. And this kit includes a gourd cup (called a Mate) and a metal straining straw (called a Bombilla), so you can drink your Yerba Mate like the pros. It's a drink that takes you back in time a bit, and gives you the oomph to face the present.
