Sirchie 3" Fingerprint Ink Roller

Constructed specifically for use in taking rolled fingerprints, the frame is heavy-duty steel. The 3" roller is of medium-soft composition, ensuring an even distribution of ink. Using the ink roller, push and roll the ink over the slab until a smooth, thin layer of ink is formed. Then, begin rolling the fingers in the ink. Repeated cleaning with solvents will not damage this roller
