As a hoarder of old RPG dice, I am constantly “inking” my dice. Either to add color to the dice for the first time or to replenish their readability after years of neglect. I use two of the more accepted methods for doing so. One is using a very fine tip marker. This requires a very steady hand, patience and a bit of boldness. About 30% of the time, I do a decent job with a marker. Even when I do, my hands and everything around me is often covered with ink afterwards.
