This Has Never Been Seen Before The Penbookmark Is A Gel Pen That Is So Flat That It Can Even Be Left In The Book As A Bookmark. The Rollerball Is Ideal For Taking Notes Because The Thermo-Sensitive Ink Can Be Erased And Written Over Without Leaving Any Residue. The New Gel Ink Is Thermo-Sensitive And Disappears From A Temperature Of Around 60°C. The Eraser Heats The Ink By Frictional Heat Without Damaging The Paper, So The Ink Becomes Invisible Without Leaving Any Residue. After Some Time In The Freezer (-10 °C) The Writing Would Appear Again. The Ink Is Therefore Not Indelible!
– Super Thin: Only 4 Mm “Thick”
– Erasable Rollerball
