Kase Air Blaster Medium Dust Removal Tool

The medium-sized Air Blaster dust removal tool safely blows clean air to remove dust from delicate or hard-to-reach surfaces such as lenses, cameras, filters, and keyboards.
The air blower is made from durable, natural silicone rubber that provides virtually instantaneous rebound for a near-continuous stream of clean air.

The nozzle has an opening that prevents whistling.
A one-way valve at the bottom introduces clean air and doesn't redistribute dust. In addition, the blaster stands on its own and can be placed on a flat surface without rolling around.
