The Pantam Series Auras are crafted out of nitrided low carbon steel and undergo several rounds of heating and polishing to acquire the grey stone-like color, desired marble smooth finish, and classic pantam timbre. These instruments are tonally clear and controlled, and the material exhibits superior strength and durability. Additionally, the body of the instrument behaves more clay-like when struck, adding more percussive elements when playing. Nitrided steel provides improved corrosion resistance when compared to other materials.
