The Zephyr style brush is made exclusively for fingerprinting purposes
and is distinctive in most crime scene cases. Shaped to pick up and retaina supply of fingerprinting powder this brush is very effective when used with a twirling, rotating motion, especially on flat horizontal surfaces. Every brush is made from a thousand fibre bundles each of these being composed of over a hundred individual treated glass filaments. It is for use with dry powders on dry surfaces. Do not use on greasy surfaces.
