The conversation to introduce a liner and scroller/pinstriper was discussed for quite a while before it finally became a reality. We tried many different blends of hair whether it is natural, mixed or full synthetic. Von Dago decided on a full synthetic which is our synthetic sable. This is the latest and greatest synthetic on the market today! It is unusual in the fact that it absorbs the paint and flows off the fibers in a controlled manner. This hair absorbs like a sponge. I knew we were on to something when Von Dago, a natural hair enthusiast, fell in love with this synthetic. This brush is offered in sizes 00 thru 1.
