what makes it better? I've heard that, but I don't know what constitutes better.The gansulin pen is way better than the bird pen. I like the bird pen, but gansulin is so much better. More expensive, sure, but way better. I have 2 gansulins, a bird pen, a Savvio, an All-Star Pro and a sulin pen from AE. Gansulin is my favorite, followed by the All-Star Pro.
