Azurahorns are of glass-fibre composite construction with cast flanges. The white colour is applied as gelcoat -  the first layer on the mould. I finish the smaller horns on a spinner to give a soft alabaster appearance.  The back of the horns are finished in a thick white Flow-coat. The surfaces are suitable for custom spray painting.  Flanges are cast in a mould using a resin / calcium carbonate mix.  The mounting holes are drilled for your driver using a template.  The horns are packed for shipping in a custom made strong double ply 7mm cardboard carton.
