Smooth!

Gave these pens as a gift to 2 medical friends and they got a good laugh from the name of the pens. Actual pens write very smooth! I bought the stormy skies set to use on the dark matter paper journals and the ink flows so smoothly it is almost as if the pen slides across the paper. Am am enjoying them immensely! Will definitely purchase more!
