I have a chunky pair of curved sunnies with their own heavy hardcase that is so big, it took up way too much handbag space. I saw the Fox and Leo cases online and thought I'd try them out. Perfect! I wasn't sure if it would work because of the big curved arms but it works really and takes up a lot less space. Good quality, excellent colour range, sturdy and well made. I've ordered a second case now for my other glasses.
