GF OP 003 004 OLIVEDESCRIPTION Our current 9772 frame which served as the base for the Crossbones is currently one of our bestselling models, originating from a style group that was first created in 1985. The 925 Sterling Silver crossbones detailing, taken from The Great Frog's logo, sits on the redesigned temple which is thickened at the hinge for both a bolder silhouette and improved stability. These are a great pair of everyday glasses with attitude in abundance.
