They are the preferred choice for tattoo body art and high-end salon professionals because their distinct color stands out and mask stains, inks and dyes during use. They are also the preferred choice for law enforcement agencies, correctional facilities, homeland security and postal facilities because they rapidly identify potentially unsafe light-colored substances.
