Dating from the late 70s by my estimate, these sunglasses have large gradient brown plastic lenses (non-corrective). The frames are marbled opaque plastic in shades of reddish brown. ‘399 Japan’ is barely visible stamped inside one arm. CONDITION: Just good. I would call the lenses pretty scratched (zoom in to see) & the frames also have some nicks & scratches. Although they do not appear bent at all, when you fold in the arms, they cross rather crookedly (final photo). Still, so cool. SIZE: The lenses themselves are 62mm across, the bridge is 14mm across & the temples are 133mm. 10% of denisebrain sales go toward saving endangered manatees through the Save the Manatee ClubThank you for helping me help this great cause! 70S Big Rounded Plastic Sunglasses With Ombre Lenses Made in Japan Vfg
