Features:

• Bi-Chromatic Latent Print Powder, 2 oz.
• Powder has the remarkable properties of appearing black when dusted on a light-colored surface and silver when dusted on dark-colored surfaces.
• Using a Zephyr Fiberglass Brush and Bi-Chromatic Powder, you can dust up to 90 percent of the surfaces found at most crime scenes.
• The greatest advantage of using powder is that the lifted prints will be black when placed on a white backing card.
• This eliminates the bother of comparing latent prints with light-colored ridges on a black background against rolled prints with black ridges on a white background. It also means that only white backing cards will be needed.
