You CAN afford to outsource that health department compliance fear! Regulation is coming; look it up. Regulation = Documentation. Solve this for cheap with PRF app. Crafted by LEGIT piercers and tattooers Conan Lea, a 28-year custom tattoo artist, designed PRF with the indomitable Steve Truitt, a 30+ year Body Modification Artist and 20-year APP Member.
