Contains five developer sheets. Each developer sheet processes up to 100 individual cards and the special Digit 10® fingerprint pad will yield up to 10,000 individual prints.
Simply roll the fingers on the chemically-treated pad, then roll the fingers on the fingerprint card, leaving undeveloped red prints. The cards are then placed in the Digit 10® unit with a developer sheet and in approximately 40 seconds, permanent, black fingerprints that meet all FBI requirements will develop.
