Very Happy with these Eyeglass Holders
To start with, I'm not mislaying my glasses any more.  That's a comfort.  These eyeglass holders are a nice design.  Being leather they're much lighter than metal chains, and don't clunk your face the way chains do.  These holders start out a little stiff, but flex up after a few days of use.  I would personally be happy NOT to have the slide at the back which I think kind of gets in the way, but I understand why some people would like it to get a tighter fit when needed.
