Hakusan Megane Oval Type *Please replace the lenses as they are prescription lenses. The prescription lenses will be removed and sent separately. - Shape: Oval - Material: Plastic (Acrylic?) Purchased around 1996 at Hakusan Megane in Shibuya Parco, with prescription lenses. The thick transparent frame has aged to an amber color. The metal parts inside the temples have also oxidized beautifully. Almost 30 years have passed since the purchase, but it's still an archive piece that can be worn. As those who love glasses know, cellulose acetate frames deteriorate if not worn occasionally. I wore them regularly, so there is some wear and tear, but there are no cracks in the frame. I hope those who like the 90s vibe, and those who like Euro vintage clothing will purchase these. Thank you for looking.
