"Cask" is the second round-shaped frame following the "Phi," making its debut as a front acetate frame. The size of the round shape is not too small, allowing for a more distinctive expression of individuality. The original T-Spine parts prevent acetate aging, and the high springiness of the double S-line temples creates a comfortable and secure hold.
