Can anyone recommend a printable label for vacuum tube boxes?

I have a sizable new old stock collection (ok--sizable for me), and can't stand my handwriting all over the storage boxes.  It's inconsistent, sloppy looking, and not clear.  I'd like to buy printable labels and I'm too lazy to experiment, take measurements, etc.  Well, maybe not that lazy, but I thought why reinvent the wheel!  

Has anyone done this?  Thanks much in advance!
