I don't know what model the back pair are and they are by far in the worst condition. The nose bridge does not fit tight and the lenses are pretty bad. Not to the point they can't be used but still pretty bad. The middle pair of Glitter Gultch and come with a box and bag. They are in good to great condition. The front pair I believe 0.4 and they have swirl marks in the lenses from cleaning but over all are in good condition. $200 for all of 3 shipped to US only.
