The popular Latent Print Sequential Processing Chart that has been found in our catalog for years is now available in pen form for use in the field. This unique ball-point pen features a hidden pull-out. Simply pull the small metal tab to extend our entire Latent Print Sequential Processing Chart. Half of the chart is displayed on each side of the spring-loaded chart. When done, simply release and the chart will retract back into the pen housing. The pen is a standard ballpoint pen and can use any standard pen refill.
