So I initially purchased the pencil, but did not love writing with the pencil. I am just not a fan of thick leaded pencils. Maybe because I am a lefty, and don't like smearing. So I asked if I could trade it in for the pen. Allegory was wonderful and happy to oblige. I love the pen. It has a unique locking mechanism that feels very tight when it clicks into the extension position. It is simply beautiful. It is my second Allegory pen (I also have the Model C), and I am not sure which I prefer. Great products.
As a pen lover, I took a chance in this when it was one of Allegory's earliest (maybe first?) kick-starter campaigns.
I haven't looked back since.
The quality of the pen itself is matched by the thoughtfulness of its presentation and accessories, and the company was quick to offer support when I had a (self caused) issue.
A quality pen, from quality craftspeople.
