The Giottos Rocket Blower is the perfect tool for safely removing dust from your equipment, even in hard-to reach areas. The durable silicone-rubber body inflates almost instantaneously so you can eliminate dust quickly and efficiently. The long, thin nozzle lets you get into even the most difficult areas. The one-way valve allows clean air to flow in without picking up dust from in front of the blower. A unique feature of the Giottos design is the class "rocket ship" feet that allow the blower to stand upright so it can't roll away from you.
