Isaac Reina Glasses Case with Strap, Black/Natural
Perhaps those that wear glasses that need to frequently be put on and then off will find this more useful than others (ahem, cheaters), but any number of things could be put into this case then pulled out for easy access. One long strap for around the neck, one shorter to be attached to your bag. Once you have it, you'll wonder what you did without it. 6.3" l x 2.9" w.
