We use polished aluminum for all of our perfume sprayer, collar and caps, so they have a smooth and shiny finish. Perfume sprayers from FEA12 to FEA20 are available in crimp, crimpless, screw and snap on types. Collars can also be customized to fit the size of the perfume sprayer. Perfume caps are available in various shapes and sizes, please contact us for detailed pictures. Regular colors for aluminum are gold, silver and black, other special colors need to be made by Pantone number. Samples are available in all sizes and can be shipped at any time. Products can be customized according to customer requirements.
