Hi Chris, and thanks for posting this info on the new long filbert!
I have many Trekell brushes and really like them. I am glad that they continue to work on the hair loss issue. It was annoying, but not debilitating in their brushes of a few years ago - brushes of any stripe are going to lose a few hairs.
Trekell folks, if you are reading this - please include a coupon in your brochures you send out! It doesn't need to be large, but your materials need a "call to action", IMO. The nice brochure does remind people of you, but it does nothing to get them off their butts and order some new brushes.
