The Sirchie Standard Size Fiberglass Brush is designed for developing latent fingerprints. Thousands of specially selected fiberglass filaments form a cloudlike, soft cluster that retains powder and eliminates the constant powder replenishment required for conventional brushes. It is produced on a perfectly balanced, black, injection-molded handle for the ultimate in control. The brush is supplied in a protective container and cap. The reduced handle length makes the kit size brush an exact replacement for conventional brushes found in most fingerprint field kits now in use.
