Fingerprint roller for taking fingerprints, working surface diameter 1 cm, length 5 cm.
Designed for rolling fingerprint paint on the working surface of glass, palms and fingers during fingerprint registration.
The roller consists of a roller and a steel handle with a bracket for installing and rotating the roller. The roller roller has a steel base with a smooth rubber tube put on it and is installed in the holes of the steel bracket using two steel half-axles that ensure its rotation. The rubber tube of the roller has no wall thickness variation, seams or unevenness. The design of the roller does not allow rotation of the bracket relative to the handle, radial runout of the roller during rotation and separation of the steel axles from the roller base during operation.
