I want a small dry box, large enough to fit a pair of spectacles, but not excessively thick. I will outfit it myself with foam as needed. Any suggestions for this purpose? minimum inside dimensions 5 11/16 x 2 1/8 x 1. The length and width doesnt make much difference to me as long as it isnt excessive, but the thickness is important as I want to be able to slip it in a pocket.

Any suggestions would be appreciated. I found the otterbox 2000 series to be the closest thing to what I want thus far, but im not familiar with whats out there.
