I use ABS pencil cases. They come in various colors and are just the thing for a straight razor. There is even a double version that fits two.My Rigarazor arrived a week or so back; it is a work of art and shaves very, very nicely. However I'm more than a little disappointed that it came without a case! Is that normal? None was pictured in the advertisement, but I thought an item of this quality and price would have one. Guess I can make or use a toothbrush/pen sleeve or similar...
I can get two shavettes in to the single case, but I don't do that with my straight razors, well, not my good ones.
