I purchased the eye glasses case as I now have 3 different glasses (reading, long distance, prescription sunglasses). If I have my large tote bag, it’s fine to have 3 separate glasses cases in there - but when I go out at night and want to wear just a small cross body bag - then all 3 glasses get squished in, the lenses get scratched and even the arms break. Using the Fox and Leo glasses cases are a game changer, as my glasses are protected, but I can fit them in my small cross over body bag - plus I have different colours, so I know which glasses to grab when needed.
