A distinguishing feature of Ptolemy48 eyewear is the use of traditional Japanese metal carving techniques. In the EMPEROR series, the core metal of the temple showcases the intricate artistry of "kebori 毛彫 carving," one of the oldest and most revered metal carving techniques. The fine lines and attention to detail in this carving technique add a touch of sophistication and cultural heritage to each frame.
