I know this may be a silly question, but what is the best most practical wallet size? I need to ask others who also understand that it is not just a wallet! I have always carried a tri fold. But not I think they get too thick. I am considering a longer one, I would think your stuff would have more room to spread out, so to speak. I don't really think I want one with a checkbook, never used one and now I hardly even write them. Also, I am currently using a gun metal and a black bag, what color wallet? Black would go with both, but I don't want to resort to the usual without other opinions to consider. Thanks!!
