Since these are only for my own use, I stick with minimal markings. Tagging the tops of the holders helps when I store lots of them together in boxes, letting me tell them apart quickly without digging any out to check the writing. I mark the holders as well.
Having just joined after submitting my opening request, I'm exploring options for staying neat. Others seem to rely on a label device when marking vials, which has me considering getting one too. Anyone with experience can mention what to watch for ahead of time? Is this the best choice or might another version suit vial marking along with overall tidiness?
