So the great travesty with these pens are twofold: 1. They don't write as smooth
as the individual Frixion pens and 2. No matter what colors you fill it with the
'clicker' portion of the pen stays red, blue and black. Urg.
So if you buy two barrels like I did so that you can have fun colors like pink,
purple and green it will still show red, blue and black & you'll just have to
try to remember what is where, which isn't that fun at all.
