Costa Del Mar Caballito Polarized Sunglasses

White Costa Del Mar Caballito CL-30 580P Polarized Sunglasses. I bought these for on the water, and by time I got around to using them, I realized they were too large for me and the return window had passed. There is one flaw that I am able to see; a slight pink shadow on the outer top left part of the frame. Not sure what it is, it could very well have been there when I bought them.
