The Inkless Shoe Print Kit is a clean and easy method for obtaining positive footwear impression. Designed for obtaining footwear impressions for comparison to suspect prints, our Inkless Shoe Print Kit won't leave dark residues behind like ink will. The footwear is simply pressed onto the yellow inkless coater, then pressed onto a 17.7cm x 35.5cm (7" x 14") impression sheet. In a few seconds, a permanent, black impression will develop. Because it is inkless, there is no mess or clean up. The kit includes one coater, good for up to 200 impressions, and 100 impression sheets.
