...I got my set of three Isographs in 1981...best things ever.

Okay so you showed us how to fill them, which is fairly self-explanatory. But How do we get the ink to come out? I filled them all and...nothing. nada. is coming out the tip.

Ik this is a old comment but for future people looking at this just shake it up and put it upside down, then just wait for the ink to fill up the nib

I think that you prime them by shaking them at a 45-degree angle. There is a piston inside the pen.

Update. I found a book that I've had on technical pens called, "The Technical Pen" by Gary Simmons. According to that book, hold it nib down for 30 seconds, gently tap the butt end of the pen several times, turn the pen upside down and tap the butt end on a table with a sharp tap. See, the holes are for air intake and the ink flows when bubbles rise in the barrel and push the ink down. So, make sure the barrel is clean and there is no ink in the air holes, etc.

Trying to find out if this ink is waterproof? Can you advise ?

[@LimitlessFrank]

I wonder if it's eye-dropperable?
