The Pen That Never Runs Out Of Ink - The Resident Architect

The Pen That Never Runs Out Of Ink - The Resident Architect:
They call this The Inkless Metal Pen. Now maybe you're asking - 'Why is it called the Inkless Metal Pen if it never runs out of ink', well because it actually does not write with ink and it does not need ink to write. It has a special metal alloy tip that does the writing.
