The Royal & Langnickel Zen Series 53 Synthetic Brushes simulate the experience of natural hair brushes. Comprised of high quality, thick diameter synthetic filaments; these brushes are ideal for acrylics and oils. The Zen Series 53 Brushes are slightly soft with an excellent snap that holds their shape better than natural bristle. The metallic, silver ABS handles allow you to soak the brushes in water without swelling, cracking, or chipping.
