The box-shaped design effectively increases the stability and anti-torque, can stand higher string tension.
The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life.
Graphene is composed of carbon atoms arranged densely in a hexagonal honeycomb crystal lattice , which has become one of the lightest and strongest materials in the 21st century. By only one gram of graphene can bear five tons of weight .
