Return to Rotring


Maker: Rotring.

The Core is Rotring’s excursion into the realm of the school pen.  I suspect the impulse behind the design might be spoken thus; “OK, let’s try to be ten times more Lamy Safari than the Lamy Safari!”  It is an extremity of design, and I think only very self-possessed teens of a particular sci-fi bent might ever have considered it for regular use.  The cap is clearly meant to emulate the fore-grip of some science-fictiony rifle, and the sway-back section lends it a certain resemblence to Serenity.

There is one item of interest, which is bound up with the tradmark red ring.  On the body, this is suggestively pointed out as the “Write On System”, and while there’s nothing in the instructions to direct its use, it is apparently designed to allow the cartridge-piercer to be very slightly withdrawn by undoing the barrel and then tugging on the red ring.  That makes it possible for the residue of ink left in the pen to get into the feed (in theory) and thus finish the exam the user should have brought a full cartridge to in the first place.

It is quite like the Lamy in that it writes smoothly with an apparently indestructible point.  If only it were not so funny looking….
