LOTUS FL-1L mouthpiece for flugelhorn; inner diameter: 17.12mm (0.67"); bore: 4.00mm; medium cup; LOTUS #1 rim; material: brass, LOTUS Golden coating: hypoallergenic, scratch-resistant and does not tarnish; this mouthpiece was designed specifically for players who usually only play flugelhorn in a big band who prefer using a trumpet cup on a flugel shank to help them cut through the wall of trombones and saxes without having to play loud and hurt their endurance; LOTUS created a fairly shallow V cup that gives you a more characteristic flugelhorn tone than simply choosing a small-shank trumpet mouthpiece; silver plated; L-Taper (Yamaha shank for USA and Japanese instruments)
