This airbrush cleaning pot simply makes life easier for anyone who uses an airbrush. The jar itself is made of a heavy duty glass which means solvent-based paints, thinners, etc. will not damage it. The lid is tight fitting and the exhaust opening has a filter to trap particles in the cleaning pot. The inlet for the airbrush has a rubber seal so that your airbrush will fit securely and help protect the finish of your equipment. Not only does this make cleaning your airbrush easier, but it also acts as a holder for your airbrush when not in use.
