You can be confident that the fingerprint powder you get will be consistent in quality every time. All of our powders are precision milled and sifted to assure quality. Our magnetic powders are made with the same care and attention to detail as our standard options. Use our fingerprint powders only on non-pourous, non-ferrous surfaces. This product must also be applied with a magnetic applicator that acts as a ”brush” by creating a ball of powder. This ball is the only thing that touches the active surface. Our magnetic fingerprint powders are available in 4 colors: Black, White, Dual Use, and Gray. They come in 3 sizes: 1oz, 16oz, and 128oz.
