Black Flys, old type. There is a scratch or crack of about 3mm on the upper right side of the fourth photo. There are also some other minor scratches, and it's an old, used item. Thank you. Also, the Black Flys sticker is still on the right side of the sunglasses. It's an old type, and the price is reduced. No claims, please. Also, if you have any questions, please comment. There is no looseness in the joint. Personally, I used it for sight fishing at Ikebara Dam. You can clearly see the scratches in the last photo.
