I recently picked up a pair of these Square Wires from ebay. They're great shades, but came with no case obviously. I've got some of Oakley's bigger square cases, but they're too large and these glasses rattle around in them. Any suggestions on a better case from other Square Wire owners? I know that the Titanium Square Wires seem to come with a smaller better fit case (below), but I've had no luck tracking one down separately.
