Lily Varnisher's brush. Hand-tied in Spain by a small operation that has been making finishing brushes for generations. Squirrel-hair blends, soft enough not to leave marks in the cured film, firm enough to lay shellac and varnish smoothly. Turned wood handles, finished simply.
Available in five working sizes — from 20mm for detail to 100mm for surface-flowing varnish. Most finishers carry two or three; the set of three is also available for shops setting up a bench.
The brush serious shellac practitioners reach for when synthetic foam will not do.
