This is my first pair I've bought, so I'm sorry if this is asked all the time but I could use some experienced opinions! Bought this pair and they were labeled as Juliet Ti02 titanium 4th gen. From what I understand 4th gen juliets do not have any serial printed on the frame; these do not have anything on the inside frame. Following the guides on here, as far as I can tell they are legit? Is the box/coin combo correct as well? Any thoughts would be appreciated. Thanks!
