Transform any standard sharpie permanent marker into a discreet and effective self defense tool. This 3D-printable insert is designed to fit snugly inside the marker body once the ink cartridge and tip mechanism are removed. This insert snaps right into the sharpie with a snug fit that wont come out without plyers. Cap also fits snuggly on concealing the print underneath. Its covert design allows you to carry a practical tool virtually anywhere without drawing attention.
