It is a new technology in regular powder applicators in which the brush itself has its reagent loading tank. The marabou long fiber brush has a mechanism that allows the fibers to be disassembled for use, keeping it protected at all times from external agents; and a reservoir which must be pressed to spread powder in metered amounts, and thus make better use of the reagent load.
High quality applicator, the best that the forensic market can offer today in regular powder applicators!
