Easily a best seller for the Grizzly Bay, it's been a bit of a signature - the classic High Mountain White in a bulb shape. It's a bit more a paintbrush, and less of a scrubber - compared to a fan.
These have incredibly soft tips and a very luxurious feel. Oh, and they BLOOM LIKE CRAZY.
This 26mm example is well suited to the typical Grizzly bore of 1 1/16"
