Pens were made due to demands of users for better writing. Pen is of two types in which first is ballpoint pen and second is ink pen. A ballpoint pen is a writing instrument that dispenses ink via a metallic sphere at the pen's tip but its ink cannot refill. Ink pen is refill again and again using ink from ink pot.This ink is manufactured by combining a variety of chemicals, which are then mixed together and heated or cooled in order to facilitate the necessary chemical combinations.
