That's a neat little set up. I'm asking about the smaller tins though, just for blades. I see where you added to that. I may have to do something for my razor though.!
Note that some (most?) of the plastic DE blade packs have a blade disposal slot underneath the wrapped blades. I reused some empty Derby packs to hold a mix of blades in my dopp kit. Since it the easiest way to bring spent blades back home.
