I drop by cigar shops every now and then to check for cool looking cigar boxes. I was very surprised at the quality of woodwork on some boxes. The shops usually have at least one stack of empty boxes for very cheap. Many of them the perfect size for razors (7 day set boxes...?).
I dust them out and put a couple few coats of epoxy and on some I make a rubber gasket seal but it's not necessary. With some silica it keeps the razors nice and dry.
