With this professional fingerprint kit, you can dust for prints on many different surfaces. The powder appears black when dusted on a light colored surface, but silver when dusted on a dark-colored surface. Lifted prints are always black. The Zephyr brush is easier to use and requires much less powder than a camel's hair brush. Kit includes: 60 cc (2 fl oz) jar of powder, 9.1m (360") roll of 5.1cm (2") wide clear lifting tape, a Zephyr fiberglass brush and 100 white 7.6cm x 12.7cm (3" x 5") latent print backing cards and instructions.
