Pen Holder, "Gothic"

This pen holder requires the purchase of a ferrule, and supplying of your own nibs. I recommend https://www.paperinkarts.com/ferrules (#globus) at 50 cents each. They are a perfect fit for these pen holders, and the ones I've been using for all my testing for fit and use.

Weight: This holder is .4oz with ferrule. In comparison, the standard Speedball(R) black plastic nib holder is .3oz. 

Thickness: The barrel diameter of this pen is 11mm. In comparison, the barrel of the Pilot(R) Parallel Pen where the fingers rest is 10mm.
