I told the receptionist at my hotel that I loved the little maté they served me yesterday and she gave me one as a souvenir!
I picked up another funny one in Caminito earlier today (a funky, dicey neighborhood in the La Boca district). It is a sort of papier machè wrapped around the gourd.
They just may be a new collectible for me!
I am also including a photo of the bombilla (straw) so you can see how the bottom, filter part works.
