Our build-up brush has been specifically designed for multitasking; the brush is rigid enough to shape carve and sculpt wet porcelain, and the long, super fine point is ideal for delicate stain application. The large reservoir allows efficient transfer of the smallest amounts of porcelain to the build up, making this brush particularly well suited to detailed anatomical build-up and dry powder technique. Sintec's Kolinsky has taken the "large brush" concept to a higher level, at a fraction of the cost.
