How to look after your sunglasses  Clean your Phat Turtle's with a soft clean cloth. Avoid optical cleaning products containing alcohol and ethanol and soapy products as these may damage the frame and lenses. Store your Phat Turtle's in a case when you're not wearing them (which will be next to never!) This will keep them safe! Try not to put your shades on top of your head as over time this puts pressure on the frame.
