Meyer 5MM (for alto saxophone). Medium facing, medium chamber specifications. I purchased this used, but I'm selling it to clear out my inventory. There are slight teeth marks, a chip on the tip of the beak, and ligature marks on the upper part of the mouthpiece, but I was able to play it normally with a mouthpiece cushion attached. Please check the condition in the photos. Accessories include a ligature and cap. I will wrap it in cushioning material for shipping. Please understand that this is a used item and purchase it with the understanding that it is non-refundable and non-returnable.
