This is a lightweight trumpet mouthpiece from Atelier Momo (currently Brass Lab. MOMO). Quoting from their website: "It is the world's lightest brass mouthpiece, and you'll experience a new sensation when playing. With just a light breath, it produces a big resonance, allowing you to focus on expressing your music." There are some minor scratches from normal use, but there is no plating wear on the rim or cup. The original box is not included. I will polish it before shipping. ■ Series: VL ■ Material: Brass ■ Cup Volume: Medium ■ Rim Inner Diameter: 16.88mm ■ Throat Diameter: 3.72mm ■ Finish: Inner Gold
