Infasurf pen

I just dug this one out of a drawer, after getting it a while back from a rep in a field I'm not actually practicing in. It has something to do with pediatrics, and the pen is a bit fragile, like kids. That pink clicker top pops off really easily, and this picture is misleading in that I had to jam the thing down to get it to stay long enough to survive the photo shoot. It's in the trash now.
