The Giottos Medium Rocket Blaster Dust-Removal Tool - Black is a practical accessory to have, allowing you to safely blow clean air to eliminate dust from sensitive or hard-to-reach surfaces. The Giottos Medium Rocket Blaster Dust-Removal Tool - Black can be used on lenses, cameras, filters and keyboards. The Giottos Medium Rocket Blaster Dust-Removal Tool - Black is made from a durable silicone rubber which provides a virtually instantaneous rebound for a nearly continuous stream of clean air. It has a long, thin nozzle that features an opening at the top designed to eliminate whistling. This nozzle is also removable for cleaning purposes. 

A one-way valve on the bottom brings in clean air and does not re-distribute dust. Additionally, the blaster stands up on its own and can be set on its side on a flat surface without rolling around.
