The air blowers of the Q.ball series are made from non-toxic, natural, and environmentally friendly rubber, resistant to high and low temperatures, and tear-resistant. They are very powerful, feature an air valve to prevent dust inhalation, and emit a strong airflow to blow away dust, making the cleaning of lenses, cameras, and filters a breeze. Giotto's patented and unique tripod base can stand upright. The medium size comes with an adjustable air nozzle for practical and safe use.
