I purchased the 4 pack of fine tip - Black, red, green, blue.
As you can see in my photo the black one seems to work great. Blue is okay. Green is marginal and the red is basically useless.
This was after scribbling around to try to “prime” the tips and get the ink to flow well. And I am always sure to store them tip side down so that the ink doesn’t drain out of the tip.
I’m surprised at the disappointing color payoff given the fact these are brand name Expo markers. But luckily the cost was low. I’ll probably be ordering some different ones instead.
