This is the 1st pair of Mambo shades I have given a 4 star to and only because the width of the frames seemed about a quarter inch smaller than I am used to.  I also am not used to semi-rimless glasses so I kept hitting them when they were on my face.  They look very nice on and are polarized!!  These have a resin frame.  They fit comfortably by my ear and at the bridge of my nose.<br /><br />Size specifications:<br /><br />Lens width: 63<br />Lens height: 38<br />Bridge: 21<br />Arm: 123<br /><br />This is a great uni-sex semi-rimless set of polarized sunglasses.<br /><br />*  I received this product at a discount in exchange for an honest and unbiased review.
