I need some help here.
I want to refill a Pantone Tria marker with some ink but I don't get how it's
My ink and markers look like these:
I took of the broad nib from my marker and I tried getting the ink in with the refill bottle but the ink is leaking like crazy when I put in the bottle tube and hold it upside down. What's the trick to do this right? I'm not supposed to put it in drop by drop, am I?
Also, how do I know when I've put enough ink in it?
