Yumba rosins are manufactured using ingredients derived from vegetable origins which help the bow hairs remain intact as well as clean from any tint. Yumba also focus on the melting and mold and filling process to archive an excellent final product. Yumba rosins are tapped from the Argentine Littoral also known as the Mesopotamian region, which is surrounded by the Iguazú, Uruguay and Paraná rivers. The tropical weather and rivers which cross the Argentine territory as well as the abundant rainfall produced in the region create excellent conditions for pine growth. The result is one of the most unique rosins in the world.
