Known as a Bombilla Straw, this Yerba Mate Filter Spoon Straw is for all types of tea and coffee. The filter on the spoon on the end of the straw allows you to drink Yerba Mate or other teas without a tea bag or filter. The straw filters for you! Made from polished Type 304, 18/8 stainless steel, it won't leave a metalic taste in your beverage.
