Harder and Steenbeck are know for their high quality one of a kind airbrushes. They have in the past broke the mold sort of say when it comes down to airbrush design. Each and every one of their German engineered airbrushes are a functional piece of art that go through an intensive manufacturing process. The Evolution AL+ is a first for Harder & Steenbeck though. And possibly the entire airbrush industry. It is an airbrush engineered almost entirely of aluminum. Because of it's base metal the AL+ weighs in at just 56g, or just less than 2 American ounces! That is less than half the weight of a typical airbrush.
