These are EFFECTOR PEARL (gold frame) glasses, also loved by Go Ayano. The camera's performance is poor, and I couldn't capture the frame's markings. Inside the left frame: "TITANIUM made in Japan" Top of the left lens frame: "PEARL" Inside the right frame: "Product of EFFECTOR EYEWEAR" Top of the right lens frame: "EFEECTOR" are printed on each part. Purchased about eight years ago from Lock Stock in Sapporo. Authentic, without a doubt. Although not used frequently, there are minor scratches from use. They are already discontinued, and rarely seen on flea market sites. Furthermore, the clip-on is quite rare. The lenses have prescription lenses, so please replace them. This item is not subject to price reduction. ◼️Includes soft case ◼️Includes clip-on sunglasses Search terms: moscot, Oliver Peoples, BJ CLASSIC, EYEVAN
