These Oxigen bulk sunglasses feature a wiry, yet strong, metal frame that includes adjustable nosepieces and comfort grip earpieces. The oval shape looks best on angular facial features, and this brand is superb for outdoor activities. Men will love the variety of colors available. Most frames are black, gunmetal, gold or silver, and the telltale Oxigen logo silhouette appears on the left lens. Available lens colors include orange, yellow, light blue, turquoise, blue and purple. These are offered in assorted packs of one dozen, which means that retailers don't have to spend time selecting individual colors.
