Hand made in pure Italian crystal from Tuscany since 1950. Benefitting from the robust nature of crystal these mouthpieces will never warp or change in shape as ebonite can. The crystal also offers a different tone quality to standard ebonite. The Sapphire model has a longer facing and bigger tip opening than the Ruby.
the crystal clarinet mouthpiece plays smoothly easy to get high notes and gives a good tone
Very good quality, it works perfectly.
