This pen is the greatest pen in the WORLD... That may sound like an exaggeration, but it's not. They write so smoothly, the ink dries instantly, and the pen tip is so SMALL, that you can literally write in between the lines of a book! It's perfect for when you need to write a lot of notes but don't have a lot of room on the page. My only critique is that these pens are on the pricier side, but they're so amazing, I just set aside a small budget for them because I can't live without them!!!!!
