-- Posted by noraa at 2:34 pm on Nov. 12, 2008 I got a Rapidograph pen set for my birthday and it turns out right after you use them you need to clean them. I know that it involves a suction thingy, and I have it, but I don't know how to actually do it. Help? -- Posted by dreamweaver at 2:36 pm on Nov. 12, 2008 Eeek... never used one or really know anyone that does. But doesn't the suction thingy look like a baby thing they use to clean ears and mouths with? If so, I would take a wild guess that you squeeze it, put it over the tip and then release. I'm surprised you didn't get any directions with it... -- Posted by Lulu Nobody at 2:44 pm on Nov. 12, 2008 http://www.methart.com/tutorials/cleaning.html What I found in a quick search. Hope it helps.
