Our Favorite Planner Pen
This is our all time favorite pen. We have many in Tofu White and also the other colors. One tweak we have is, that although the ME Gel Pens write super smooth with .5 tip, we prefer a thinner nib. The Uniball Signo 307 .38 refills fit perfectly and gives us the pen body we love with a super comfortable grip, and the thinner nib that works for our minimal planning style.
The Kokuyo Me Gel Pen has a unique grip with one flattened area to rest your thumb so the rest of your fingers can curve comfortably around the barrel.
