Most custom printed pens live a short life. Given away by a corporate company but of such poor quality that even though it's free the receiver does not want it. This is different with the Original Floating Action pens. This is not your standard custom printed pens. The print is made on trasparent foil, inserted into a clear platic tube, which is then filled with liquid. This creates the floating action effect, where animals can move, cars can drige and the conveyor belt can load cargo into a truck. Your imaginations sets the limits and this is why the floaty pens are so popular.
