So I decided to make a holder for them so they would always be accessible when I needed to use them and to help de-clutter my desk.
After a bit of thinking I noticed that the body of the pens was slightly tapered, they were 15mm at the base and 17mm towards the tip, so I came up with this solution using a series of 16mm holes to hold the pens in place inspired by the test tube racks we used to use when I was at school.
The whole project was done in a day and that included about 3 hours waiting for the various coats of paint to dry.
It is made of an offcut of 1mm thick plastic from an old picture frame that I had to cut down to the correct size, but you could just as easily use a CD hewel case or similar. It also incorperates an even smaller offcut of 3mm thick perspex for the 2 sides and 2 supporting brackets, although you could probably use 2 bits of the 1mm thick plastic glued together instead.
