This pen takes a little...
This pen takes a little dexterity to load and change - you have to look down the
open barrel and push your refill into one of 5 holes until you feel a small
click. The buttons depress very smoothly, stay down while you're writing, and
pop right back up when you press a different one. The pen body is completely
smooth, and I love how the bottom is clear so you can see all your pen/pencil
tips lined up.
I'm so glad someone came out with a multi-pen that's this customizable. In mine
I have a black gel ink pen and 4 mechanical pencils (with graphite, red, orange
and blue leads). I LOVE IT, It's all I need for writing, sketching or drawing on
