The small black Giottos Rocket Blaster Dust-Removal Tool safely blows clean air to eliminate dust from sensitive or hard-to-reach surfaces, such as those on lenses, cameras, filters and keyboards. It is crafted from a durable silicone rubber that offers a virtually instantaneous rebound for a nearly continuous stream of clean air. Its long, thin nozzle features an opening designed to eliminate whistling, and can also be removed for cleaning. 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.
