Answers: How much metal does the Forever Pen leave on paper?

• inkless pen physics
• silverpoint drawing technique
• metal oxidation on paper
• Forever Pen wear and tear testing

What it concludes

• The Forever Pen leaves metal residue on paper that oxidizes over time, turning a yellow-brown-gray color.
• The Forever Pen loses about 0.028 grams of metal per colored page, meaning the tip can color about 17 pages before wearing out completely.
• The Forever Pen is not actually inkless; it deposits microscopic metal shavings on paper just like any other metal writing instrument.
