A revolutionary improvement in brush filament retention, which is the DRS - Dual Retention System DRS means that each tuft is stapled into the brush back with the food grade stainless steel staples and after that, the epoxy resin is floated in. As a result, the resin permeates the bottom of the tuft hole, covering the filaments and staples as it goes. The resin seals the face of the brush securing the filaments and prevents the accumulation of dirt and moisture in the tuft holes. 3 Reason to choose Resin-Set DRS brush ware: 1) Easy to clean, 2) No filaments loss 3) No accumulation of dirt, moisture, and so possible pathogens
