The fiberglass fingerprint brush is designed to detect fingerprints with non-magnetic powders, as well as to refine the detected fingerprints with magnetic powder.
Due to the lush feathering, the powder distribution is uniform, the fingerprints are not erased when the brush touches the surface due to the softness of the bristles.
The fiberglass fingerprint brush allows you to detect fingerprints and does not contaminate the background.
