Japanese eyewear label Tana-Gokoro has just released a collaborative effort with fellow Japanese brand hobo in the form of a celluloid fiber-based optical frame. The thin classically-styled frames feature simple silver ornamentation near the bridge and temples for a professorial look. Also available with tinted lenses, the frames are priced at ¥30,240 JPY (approximately $340 USD). More details on retail availability are expected soon.
