Blitz-Green™ Magnetic Fluorescent Powder is a highly fluorescent green latent print powder. It fluoresces well when viewed under 254nm, 365nm and 450 to 490nm wavelengths of light, but is particularly sensitive to ultraviolet wavelengths and light wavelengths from 540nm to 550nm. It is applied just as any magnetic powder and adheres well to most glossy papers and smooth plastic items.
