This is a mouthpiece for a flip head joint, which is used by holding a flute vertically. There are two types: AM-1 and AM-2FLOW. This is the AM-2FLOW model (list price: 25,000 yen). It seems that some people own both AM-1 and AM-2 and use them differently. (From YouTube) Purchased new from an authorized importer in January 2026. Used for about 10 minutes each time. It can be washed with water, so I cleaned it immediately after each use and stored it in the case. There are no scratches or stains, but this is just my personal opinion, so please refrain from purchasing if you are concerned about minor details. It will be sent in its original box, along with replacement rubber bands for the inside of the mouthpiece. Immediate purchase is possible. Thank you.

The breath resistance is slightly stronger. Players who don't want to use too much air, especially in the high register, may prefer the Flow model. Recommended for classical players and beginners. The sound spread is less than the AM1, and the tone tends to be relatively soft. Also, you can play a longer note with one breath compared to AM1. [Mouthpiece only (no metal neck)] - Easy to learn embouchure, and sound formation is easy like a recorder/whistle. - Precision laser sintered one-piece design - Ideal for beginners and classical flute players who want to play with less air. - Includes 3 O-ring seals that fit the curved neck (+ 3 spare O-rings) (※ Metal neck is not included) Click here for product details ↓ https://celtnofue.com/fliphead.html#5 #flute #fliphead #fluteheadjoint #fluteparts #pops #jazz #improvisation #classic #band #saxophone #clarinet
