Sirchie Visible Stain Detection Powder, Black/Purple, 2.5oz (74ml)

The Sirchie Visible Stain Detection Powder (Black/Purple) should only be used indoors, subject to the statements regarding their use in the discussion to the right. A visible stain powder should be selected based on its natural color blending with the color of the target object. It should be carefully dusted on the object with a soft applicator brush. When contact with the object is made, a transfer occurs. When the transferred powder contacts moisture, such as perspiration, facial fluids or water, the powder goes into solution and a resulting vivid color appears. Visible Stain products cannot be removed from the surface applied to. The Sirchie VS305 is a black natural color and stains purple.
