Craftsmen at TART OPTICAL were "shotgun": signature on temple

This frame is TART OPTICAL ARNEL in Amber color and in 48-22 size. Craftsmen at TART OPTICAL were "shotgun" when they engraved their signature on inside of a temple. Some frames were shot more than 2 times so their engraved marks are "doubly-blurred". I adore this roughness of TART OPTICAL.
