WaterWriter® is our solution to the problems of writing in wet, greasy or gritty conditions. It is pressurised so works when held at any angle, writes on all our waterproof papers (and any other paper) without smudging and has a specially moulded outer to give ultimate grip. Importantly there is no spring mechanism in the pen, so grit/dirt cannot penetrate the inner workings. It really is the hardiest, most comfortable, pen out there. Put it in your pocket and it will not leak.
We have incorporated into the design a well ventilated cap to assist with safety in case the cap is inadvertently swallowed. However this is a professional item and should not be given to children to use.
The triangular top minimises roll on table top whether in boats or planes.
As in the image on the far left it can even write under water.
