Calabria PFR-30 Metal Folding Reading Glasses - Lightweight & Durable for Reading, Travel, and Work - Perfect for Books, Computers & Outdoor Use

Very sturdy and comfortable fit. Not too big on the cumbersome case. I know it's for protection but it just adds to the hassle of the unfolding process. No big deal. I can just put in a small cloth bag. The glasses are sturdy enough unless you're in construction of plumbing. lolquick, easy. look great The design looks great. They wear great. I am a proud owner and will suggest to all my friends.
