This five pack of Blending Brushes is from Crafter's Companion. These brushes have super smooth bristles which are designed for blending ink. They are dense and very soft, which results in seamless coloring blends. These brushes have an easy grip handheld design for perfect control. These blending brushes work perfectly with the Spectrum Noir Duet ink pads (sold separately). Each of these brushes comes in its own plastic case with a sheet of color swatches so you can organize them by color. These brushes are designed to last a long time because there is minimal ink absorption in the bristles so the ink will last longer and make the clean up easier.
