PARA RESABLE: This brush is a highly resilient brush with a blend of pure weasel hair, and has a more supple elasticity and paint content. The tips are also well matched, so they are the most effective for delicate expressions. Longer tips provide better paint content and longer curves. Also great for finishing sign brushes.
