Ok.....but if they don't want you to open the ink they should tell you that right off the bat.
To fill ya'll in: a bunch of us took the Copic certification class last summer at CHA. So they give you a nice baggie full of markers/different kinds and refill ink. I had NEVER seen the refill inks before and thought they were a new kind of marker---WRONG! Learned the hard way.
About half way through the class Marianne addressed the ink. (Saying that she hoped no one opened her ink....well, a rat at my table blabbed that I had already opened mine!)
Thanks for the reminder to be mad at "her" again Kim! (heheee!)
