Another edition of the Cult Pens Mini Fountain Pen! This time, to celebrate our 15th birthday, it's in a lovely dark blue colour, to match the main colour used for Cult Pens.

A new colour edition of the Cult Pens fountain pen!  The Blue has a brushed aluminium barrel and cap, anodized in a deep dark 'Cult Pens' blue, which contrasts nicely with the polished chrome highlights and brushed steel clip.

We've always liked small fountain pens. That's why we made the original Cult Pens Mini! After all, what's not to love about a good quality fountain pen that can be with you all the time?  We had perhaps the widest range of pens and pencils anywhere in the world, but we still hadn't found a mini fountain pen that had everything we were looking for. They never quite seemed to tick all the boxes for us.

We might be a bit on the obsessive side with pens, but we want a long list of features:

• It needs to be small and slim enough to fit neatly in a pocket, or in most organiser loops, but still big enough to write with comfortably.
• The barrel should be metal, so it's good and strong. If it's going to be carried around in your pocket or bag, it needs to be able to stand up to a bit of use.
• The cap should screw on - if it's going to live in your pocket or bag, you want to be sure it will stay securely capped.
• There should be a good metal pocket clip, to make it easier to carry, and to help hold it in place in organiser loops.
• The actual writing experience is still important with a small pen, so the nib needs to be smooth and reliable too.
• It should use standard international cartridges, so there are always plenty of choices for ink.

With a list of demands that long you'd be forgiven for assuming we'd never get the pen we envisaged. However, by working with Kaweco (creators of numerous high-quality German pocket pens) we were able to draw up some plans for a pen that we felt was, quite simply, the best a pocket pen can be.
