I love this pen. I love just looking at it. I love writing with it. Being that it's made of wood, it makes sense it would feel more natural in the hand than a piece of plastic. The nibs easily slide in and out, yet are held firmly. Measurements: finger rest - 3/8", the wider part above the finger rest is only about 1/16" wider, with the base below the finger rest roughly 1/2". It feels comfortable to me, having moved from a Speedball.
