Why does the Pen cost as much as it does?

We always use the best materials we can get our hands on. For this project we've used premium brass and hard anodised aircraft grade aluminium. Each part is individually machined in a laborious low volume production machine, then every part needs to be set up by hand and slowly cut to ensure the fine tolerances are maintained to make sure each part fits together perfectly. This all adds to the time and expense of making each pen. 

We wanted to create a piece that was less mass-manufactured to allow a more unique design that could really capture the magic of the engineering involved.
