The 15 ml airless squeeze tube has a cosmetic pump applicator that prevents air from entering the tube. It is "airless". 

Our proprietary formula was developed by professional trumpeter Ken Robinson after researching studies conducted on endurance athletes and with input from fellow wind musicians and professional chemists.  Our unique blend of ingredients works fast, is highly effective and easy to apply. Lip Renew removes lactic acid from muscles, allows oxygenated blood to enter them and reduces swelling. It DOES NOT CONTAIN wax, petrolatum or camphor so you never have to worry about it affecting your playing. You can use it while you play without wiping it off. 

Finally, wind musicians can simply focus on making beautiful music without worrying about getting through those challenging gigs.
