So, I bought a new 1½" Richeson 9010 brush from Jerry's Artarama on-line without having seen one before. I'd imagined that the bristles would be shorter than they are on this brush (about 1½" or so) ... which makes me wonder if this is the "magic" brush I have heard so much about.
Here's what I bought: Richeson Series 9010 Synthetic Flat, size 1½" (Jerry's #29125 - 3rd one down on this page)
I'd appreciate it if someone can verify this so I can return it if need be before I use it.
That's the real deal.
