This intermediate flute headjoint is made in solide Sterling .925 silver. It is the same headjoint that comes with the 300 series from Yamaha like the YFL383 or YFL372. This headjoint allows you to upgrade your flute by offering a richer tone and more power compared to regular student headjoint in silver plated nickel. It fits most flutes and we can adjust it to your instrument in one of our repairshop.
