Benefits of Lambskin: All of our Professional grade products are made from 100% Pure Lambskin. Lambskin is naturally the best material available for the application of most oil-based finishes and oil based sealers. Because of the density of Lambskin, it is able to absorb more finish and, therefore, release more for a faster/smoother finish. There are between 40,000 - 60,000 wool fibers per square inch on a lambskin applicator. Despite recent efforts, technology has failed to compete with the abilities of Natural Lambskin. Lambskin is the preferred product of industry PROFESSIONALS.
