Designed by Gamblin. Made in Germany using synthetic bristles. These bristles are not only animal-free but made for the job. Unlike animal hair bristles that load heavily and break over time, thin-fiber synthetics that mop varnish, or single-use sponge brushes that create bubbles, this brush is designed to load and deliver the correct amount of varnish. And when it comes to durability, theres no match. Dedicate this brush to varnishing, clean the bristles with soap and water, and hang dry.
