A bombilla is a filtered straw for drinking mate tea. It means "small pump" in Spanish. Indigenous peoples such as the Guaraní used to cut thin bamboo or reed stems to make straws. Spaniards began manufacturing them with silver, which was abundant in mines. Today, in addition to silver, there are many types made of metal products such as alpaca (called alpaca in Spanish) and stainless steel. They are about 15-20 cm in total length and have a tube thickness of less than 1 cm, excluding decorations. Material: Alpaca steel (Alpacas) Size: Approx. 19cm To cool the hot mate tea as it is drunk,工夫 (kufū - ingenuity/effort) is made by attaching a metal decoration in the center of the straw part or by creating grooves on the straw surface to increase the surface area and facilitate heat dissipation.
