SVST's 7mm nylon rotobrush was designed as a do-everything rotobrush for those of you who don't want to deal with multiple bristle types. It works just as well in a progression as an intermediary brush for colder weather wax removal, typically used after the shorter bristled, 3mm brush.
If you're just starting out with a rotobrush system, this would be the brush we recommend.
Use with 150mm Roto Brush Handle only.
This is the best quality tools I have seen on the market for a competive price. I am a field service trouble shooter and am working with all kinds of tools daily . all these tools both brushes and handle are made out of machined aluminium rather than plastic.
