This is a set of neck screws and lyre screws, commonly known as "Hana-neji" (Hana screws), made by Hanaoka Wind Instrument Workshop in Nagano Prefecture. Exclusively for Selmer saxophones, regular size, silver-plated finish. When installed, it produces a powerful sound, but the resistance doesn't increase significantly, resulting in very balanced screws. The listing includes only the screws themselves. They will be shipped in a plastic case via Nekopos (a Japanese delivery service). Please check the photos for the condition and purchase only if you are satisfied with the current condition.
