Safariland Lightning Latent Fingerprint Powder, Silver/Gray, 2oz (In Plain Jar)

Lightning Silver/Gray Powder is recommended for use on all glass, metallic, highly-varnished surfaces, hard rubber, safes, blue-steel guns or dark-colored surfaces. Lifts developed with Silver/Gray powder must be placed on a black backing card for optimal contrast. The manufacturer recommends using a different Zephyr Fiberglass Brush for each type of powder that you use.
