Spray any liquid! The Jacquard You Can Refillable Air Powered Spray Can looks and feels just like a regular aerosol can. Fill it with your favorite paint, medium, or other liquid and use it over and over again. The reusable spray can is powered by compressed air. Pressurize the can with a bike pump or compressor and you’re ready to spray. The eco-friendly YouCan is free of any irritating propellants. There aren’t any odors or fumes, so you can spray indoors. When the can is empty, don’t throw it away — just refill and spray again.
