Fluorescent powders are useful on multicolored surfaces. Be careful not to mix powders on a single brush. The most classic mistake observed in fingerprinting is to insert the brush directl into the powder container. This leads to damaging the bristles, often leaves contaminants in the powder, and leaves too much powder on the brush.
