[Drum heads made of strong aramid fiber instead of film material] By using Technora, an aramid fiber said to be eight times stronger than steel, there is less difference in tension between the center and periphery compared to heads made of film material, resulting in a more uniform sound throughout the entire head.This reduces the feeling of congestion, especially when tuning at high pitches, and allows for the maintenance of a more extended resonance. Furthermore, the strong contractile force of genuine leather and the strong tensile strength of aramid fiber make them functionally similar as drumhead materials, and it can be said that cutting-edge synthetic fiber technology ensures a commonality in membrane vibration with traditional genuine leather. Made in Japan, each piece is handmade. Material: Aramid fiber, Technora Thickness: Thinner than TE00C (thinnest among aramid fiber and Technora materials) With coating
