This German synth knot is way better than the synth knot on the cheapie starter brush I bought years ago. Close to or just like natural fiber in "latherability", backbone, and those other know-it-when-you-feel-it properties. I like the quick-drying and easier-to-clean (in my opinion) aspects of synth knots. Many thanks to AP for making this available in the Rubberset 400 reproduction.
