I'm sure all of us have heard the famous statement "nothing lasts forever", but some innovations have proved this statement entirely wrong. Similarly, in the world of writing instruments, Napkin has done the same and offered us with an innovative range of writing instruments designed to commemorate the word "forever". Forever writing instruments are equipped with a unique inkless tip - ethergraf. These tips are made from special metal alloy. When pressed against paper, ethergraf tips create permanent lines via oxidization. The caliber of the tip depends upon the quality of paper, so if you prefer darker lines then it's best to go for high-quality papers brands like Rhodia and Filofax.
