Клей с наклеек на пакетиках с линзами просачивается сквозь пакетик и пачкает линзу (Растит. МАСЛО , ватный диск, потом хоз мыло и вытереть осторожно помогло лучше всего) Manufacturer! The glue from your QR code stickers on the lens bags seeps through the bag and spoils the lens. On the red colored REVO lens, a square mark from the sticker is clearly visible in the center. I could not remove it 100% with a cloth, soap, or vegetable oil. (OIL, cotton pad, then laundry soap and wipe gently helped the best) best of all, in the end, the trace is visible by the LED lamp. I RECOMMEND putting your bag of lenses in a ADDITIONAL glue-tight bag. cellophane. polyethylene. and then glue a sticker with a qr code on it. the lenses will be clean. at least in the case of colored mirror lenses. everything is very visible on them. the arm of the glasses scratched the lens in the glasses. 4 mm long. we need a good protective COVER ON the SHACKLES for transportation!!! All the best!
