This once-off Black eagle brush in rainbow resin is fitted with a 28 mm synthetic Tuxedo knot. If you are in the market for a synthetic brush this one is a sensible choice as it is priced low and ready to go. Part time brush maker Bradley Rautenbach has a passion for fine hardware and it shows in his products. His badger knots are sourced from a knot monastery somewhere in the Himalayas where a band of badger-monks dedicate their lives to finding and grading the best badger hair the planet has to offer (only kidding but he is pretty secretive about the source) He likes working with resin and ebonite, and produces a lovely range of individual handles to supplement his top class knots. This brush stands 108 mm tall with a 52mm loft, and weighs in at 76 grams.
