Don't worry about a box until you feel you can control your RAD. Because if you buy a box you might as well buy a dozen so they all match because your acquisition disorder will start to speed up and a dozen boxes will quickly be filled.
I've set a firm number for my rotation and a rule that if I see one I want, I must sell one to keep everything level. So far it has worked because I find it impossible to decide which of my razors I no longer like and am willing to replace. The only reason I will add without selling is I still don't have a custom and a NOS (thought I had one, but it was a eBay scam I fell for).
