Perfect in form and function!
I purchased this for my wife, who has prescription glasses and sunglasses. She does not like the bulky cases that come with the glasses and hates carrying two cases. This works perfectly! It is very slim and easy to slip in and out of a purse or coat pocket. I will note that it is quite slim meaning larger glasses (especially oversized sunglasses) may not fit. But, for my wife's "normal sized" glasses and sunglasses, it works great!
