Manufacturer Part Number (MPN) : NGCL-03-01If you wear glasses of any kind--prescription, drugstore readers, safety, or sun, you want to protect your fragile and expensive glasses from drops and scratches. Also, chances are that every now and then, you lose track of where you put them. We designed our Rugged Hard Shell Optics Case to solve both of these problems. This protective case features a molded deviated foam construction, with a rugged hard-shell exterior, that provide crush protection for your glasses. Available in two sizes (Medium, to fit regular-sized eyeglasses and sunglasses, and Large, for safety glasses and wider-framed sunglasses), this zip top-loading case is made with a durable, weather-resistant hard shell exterior that keeps glasses safe and sound. A sewn-in microfiber cleaning cloth is always at hand to keep your lenses clean, and the durable clip attaches securely to belts or straps up to 2 wide. This means when you put your glasses in it, they are protected and ready when you need them. Problem solved.
