Wow! That one above from CVS is sweet! Not sure if there is anything to add but I have a car stereo face-plate plastic case/box that works to hold 2-3 razors... Same thing where you have to use something to make inserts but, otherwise, good and sturdy case that you can often find cheap or free.

If you don't count out the cigar box idea check this one out:

... I picked one up from eBay a while back and it is really nice! These must be huge cigars or tubes because even SR's in boxes fit in there and then slightly stack over to one side but the case is monster big, super padded and really looks great just sitting there. I threw in a few dessicant packs top and bottom and the thing is working perfect!
