This temple is inspired of "bow". A best balance between hardness and softness is expressed only in the direction of thickness, making the most of the characteristics of β-titanium.
Specifically, by making a thick part on the front side, elasticity is further toward the end side. Due to the difference between the front and back curves, the front side is more inward, The end side turns its power
outward. We are trying to touch the tip part with a surface not a pinpoint. You will get a much more comfortable fitting.
