Three super-tough guards, engineered to protect your spray can nozzles from drops from as high as 48 inches and from being tossed around in your purse, bag or toolbox. Place the guards in the closed position for transport or storage. You can also personalize your aerosol products with your favorite colors which can also be mixed and matched, (think team colors). The guards are tough enough to survive multiple drops and can be reused many times. Then, when your can is empty, replace the Nozz-L-Topp guard onto a new can and start counting your savings.
