Yerba Mate 40pk Union Suave teabags

My wife bought a box of these yerba mate tea bags some time back and they've lasted well. I normally drink yerba in a proper mate, with a thermos, Uruguayan style - the biggest mate drinkers in the world. I get 3 cups out of each bag: once empty I refill the cup and then refill it again. The mate stays flavoursome and fresh tasting, so the 40 tea bags actually represent at least double the amount of cups. The flavour is nice and genuine - not some watered down facsimile of an original mate in a gourd. I'm buying this mate again.
