Great pen
My favorite pens on the market. I love the way these write. If you prefer a smooth roller feeling to your pen this may be a bit scratchy for you but they are small, compact, and very long lasting.

I love this pen
I love these pens. I started using them years ago. They last for a long time. Very light and easy to hold. I'm not a heavy writer, so this pen's ink flow is great. I don't have splotches on my paperwork. I would recommend them to anyone looking for a nice, light weight, comfortable pen.

Finally found a good blue pen!
The pens write so smoothly and the color is a nice bright blue. They are small and narrow for easy grip. It dries quickly and does not smear. The only thing I would suggest is they add a grip section to aid in comfort and slipping for such a narrow pen.

Raw
Best pens I’ve ever used. These are actually the ink pens I use because I love the raw feel they provide.

Fabulous coverage, fabulous tip
These are awesome. The ink is clear, dries quickly and doesn't bleed - depending on the paper's weight, of course. I love the medium points, too.

Los he utilizado durante 3 meses, una de las piezas me ha durado hasta ahora y le doy uso diario. La tinta parece de gel, pero es de mejor calidad, y es muy comodo para escribir, ademas de que es elegante. Cuando me los termine sin duda comprare otros.

Simply the best pens out there. I have hundreds of them and HATE using other pens now. These don’t dry out until they’re empty, even with the caps off!
