I have realised on speaking to a new P-2 owner Mr F that I have not once mentioned its size! It is a total of 137mm long, which is quite short, deliberately so – it is a (space) travel pen after all! It also appears smaller than conventional serious ‘man’ pens because the cap is the same diameter as the barrel. At 28 grams or so (depending on material) it is quite light or as I like to say – just right. You remember the famous match-cut scene from the beginning of 2001 A Space Odyssey – the bone being thrown into the air?
