Design group ENSSO has launched a “scale ruler fountain pen” for architects, featuring 12 imperial and metric scales. Having launched on Kickstarter, the pen is now available for pre-order, made from 100% space-grade aluminum.
Laser-engraved into the solid matte black aluminum are 12 scale markings, denoting 1:20, 1:50, 1:100, 1:200, 1:400, and 1:500, as well as 1/32, 1/16, 1/8, 1/4, 1/2, and 1. A German-made nib manufactured by Peter Bock Co. is available in fine, medium, or broad stroke.
