Warranty: We warrant Costa Sunglasses against defects in materials or workmanship for the lifetime of the product. Costa handles every repair or warranty claim directly. If you should have a problem with your Costas, please refer to the Repair section of Costa's website. Costa will repair or replace, at our option, any product determined by Costa to be a manufacturer's defect. Since eventual wear and tear can be expected, reasonable repair charges will be levied if repairs are necessary as a result of normal wear, scratched lenses, broken hinges, accidental damage, misuse or any other problems determined not to be defects. A small processing fee will be charged for each warranty claim processed.
