From the pros at Crap Eyewear, these sunglasses are handcrafted with biodegradable bioacetate. Equipped with CR-39 lenses + 100% UVA/UVB protection. Finished with durable 5-barrel hinges and custom wire temple cores for added strength and superior fit. Designed and tested beachside in Los Angeles, Crap Eyewear is an independent sunglass brand born in reaction to an expensive and often all-too-serious eyewear market.
