This is a fool proof bombilla for enjoying Yerba in any mate or mug. Made from high tech polymers that will not leak and a polyethylene food grade drinking tube. The strainer has a very high mesh screen that will not stop up or allow leaves to get through and a brass weight on the bottom to keep it in place. This will pull lower than any bombilla on the market ( less than 1/4 inch from the bottom). You can cut it down to your favorite size, use it with travel mugs, tumblers, or sport bottles. Dishwasher Safe.
