Thats what I use to hold my PSK. I like it better than the altoids tin becuase it is water proof already and easier to get into. Plus, the ability to stand on it doesn't hurt either.
The only draw back is that it isnt very pocketable, compared to the Altiods tin. So I carry it in my work bag, which is always around me and when I go to the field I have another that I carry for that!
