I don't know what it is about my office, but there's some sort of space time continuum around my desk that sucks up all spare pens and highlighters. Similar to the case of the single sock left in the washing machine, there just seems to be an issue with finding and holding onto writing devices. Hopefully the biro lamp has enough pens dangling from its shade to keep your hands ink stained for the following year. Every pen works, and you can attach new ones if they ever run out (or disappear).
