Düller is a stationary brand developed by I.D.E.A. Recently, they paired Dietrich Lubs (Braun) and Naori Miyazaki (I.D.E.A.) together to make a small stationary collection, consisting of a ballpoint pen, fountain pen and mechanical pencil. The pieces are made using aluminium and come packaged in a notebook made from recycled Green Aid paper.
I absolutely love the way the black of the outer shell is contrasted ever so subtly with dark-green highlights.
