Emerald, is virtually a professional standard of comparison. Ideal for classical and symphonic player. All Pomerico mouthpieces are hand finished and may have slight manufacturer imperfections. Every mouthpiece is checked for quality before they are sent from Italy to us and before we send the mouthpiece to a customer. They are packed and shipped to ensure the safest possible transit. If a mouthpiece is received damaged, Weinermusic must be contacted immediately on receipt, or no refund will be issued. Standard mouthpiece trial policy and fees will still apply to ALL Pomerico mouthpieces, even with slight cosmetic issues.
