The large black Giottos Rocket Blaster Dust-Removal Tool safely blows clean air to eliminate dust from sensitive and hard-to-reach surfaces, such as those on lenses, cameras, and filters. 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 doesn’t re-distribute dust. The blaster stands up on its own, and can be set on its side without rolling around.
