So disappointed :-(
The measurements state 3 inches, but turns out that's the circumference, rather than the width, so it wasn't wide enough for my large Calloway sunglasses.  Luckily the case was inexpensive.  I didn't return it because the return shipping charge was almost as much as the cost.  Maybe eventually I'll find another use for the case, but for now it's collecting dust.
