Oh no my microns are running out and I’m nowhere near an art store
(PS pen tips run out way sooner than the ink, fwiw for you trad artists out there)
OK so actually a legit tip for micron users: to squeeze a little more life out of your non-replaceable tips, “crack” em. Press the side of the tip to your paper, push down, and roll it around a little. It should make a little crackle sound.
