Frequently, a check needs to be examined both for latent prints and for handwriting. To avoid leaving any new latent prints on the check while examining the handwriting, place the check in an acetate sleeve or zip-lock bag. Some questioned document examiners prefer our 4" x 9" sleeves as they are stiff and easy to file in a box or cabinet. Other examiners prefer our 4" x 9" zip-lock bags. Whichever you prefer, the sleeves or the zip-closure bags, we have them.
