Beechler Bellite Metal Mouthpieces are cast from the finest surgical stainless steel. This material is averse to corrosion, breakage, or change in playing characteristics. They are cast by the time-honored lost wax method, at a temperature of 2000 degrees, and will maintain consistent durability. The hardness of this metal provides an ultra-fast response time to bring out the brilliance of the overtone series. The Bellite Baritone mouthpieces have an open baffle. Ligatures and caps are provided with all Beechler Bellite mouthpieces.
