Dual Contrast Fine Magnetic Fingerprint Powder

Dual Contrast Fine Magnetic Powder features ultra-fine nano sized particles which provide excellent contrast on both light and dark surfaces such as glass, plastic, ceramic, and other surfaces which require finely ground powder. White or Black backing cards may be used to provide a sharp contrast with the resulting ridge detail. NOTE: To prevent clumping, our powders include a desiccant canister inside each jar with a capacity for absorbing moisture.
