Refilling ink cartridges is rarely dangerous but frequently messy. The other day I had a magenta cartridge spew about 5 ml. back at me. This was the result:
It also managed to spatter my shirt and pants, but they got nowhere near the degree of coverage my face did.
A good washing with Lava™ soap cleaned it off, and luckily for my eye our inks are non-toxic. But honestly, wouldn’t it be best to let us deal with all the potential mess involved with refilling ink cartridges?
(If it had been closer to Halloween I think I might have kept this “makeup” for Trick-or-Treating)
