    Beautiful color!

    The sky blue is the most beautiful color ink! Such a unique color, Everyone tried to steal the pen away from me

  • Lindsy


    This is the best pen ever. Extremely smooth writing, needing very little effort to write, other pens require pulling across the page to extract the ink. This just glides. It's marvelous. only downside --- i hate all my other pens.

  • Katie

    Love these pens!!

    I bought a couple of these pens on a whim at a Staples display, and I'm so glad I did! The quality of gel is great, blue color is my favorite, and the ink goes quite a long way! I used it almost everyday for months before it finally ran out. Went back to the store specifically to buy more, but since they no longer had any, here I am.

    I love this pen. Just switched from BIC because their pens kept leaking. This is the best pen I have ever used. I am left handed and it dries super fast.
