It's huge. I got one for my OCP Gascans, and they rattle around. It's the only case I have that's large enough to fit Eyeshades.

it's great it comes with your etched OCP order. But.... for my CROSSHair they're not so good. They're only padded in one side, and my glasses have been bent up several times, severely. I had to go get another aluminum vault. The OCP case is a good display thing. Not so good for use.

These came free with my last OCP purchase as of 3/2008 when you get the lenses engraved, and glad they did! A little bit of treasure to go with my one-off custom Minute 2.0's. LARGE case fits just about any of my folding pairs, except the X-Metal XX's that require their own special case....

This case is awesome!
It fits a wide range of glasses. Some seem to move around a bit but store them in your microfiber bag and they will be fine.
It is very durable and provides good protection just as all vaults.
Best part is that not everyone can have one.
