Copper Cork Plug with Crown 55x19mm

This flute headjoint cork plug measures approximately 55 × 19 mm (2.16 × 0.74 inches) and weighs about 24 g. It is constructed from a combination of copper, metal, and natural cork — offering structural integrity and acoustic compatibility with standard concert flutes. The integrated crown provides secure positioning and stability within the headjoint tube.
