2D Pen turns into a 3D pen very cool

I never thought I’d see the day when man would develop a pen so small and flat that it could actually be carried in a shirt pocket! But the Falter 2D Pen manages to do just that since it comes as a flat-packed kit that you disassemble and fold into a 3-dimensional body for a standard ball point ink cartridge. The handmade kit comes with a key that makes it easier to properly bend the metal as per the instructions.
