Fun one I thought I would share. Ratchet set my dad gave me YEARS ago (like 30 of them). It has rattled around in pretty much every vehicle I have ever owned. I keep a 10mm in this case, as well, so a slight modification to the original but the rattle is significantly less and the sizes are much easier to read. I had a replacement 5/16 socket so it is a little deeper than the others. The division signs did not show up in my print probably just a little small on the text size.
