Bureau Fingerprint Ink Pads will take thousands of fingerprints and are always ready for use. The stored Porelon ink rises to the surface of the microreticulated thermoplastic resin pad through capillary action.
The non-toxic, nonfading, permanent ultra-black Porelon ink dries in seconds on all types of record cards.
The pads are 5.25″ L x 2.75 ” W x .5″ H.
