Thank you for viewing. I'm not very familiar with this, but the engraving says "Beret DN." (DN = Dark Navy) This seems to refer to the color of the lenses. β-titanium temples. I believe I purchased this at ESTNATION. I haven't used it much and have been storing it. This is a USED item, so please refrain from purchasing if you are looking for a perfect condition item. The accessories are as shown in the photos.
