Sigh! The examinations are over. And you probably don’t want to look at the books and pens that were hounding you. But we want you to glance at the little pile of ball point pens strewn on your table. All set to throw these away and buy a fresh set?

A ball point is the most commonly used variety found across the world. conservative estimates say 100 million of these pens are sold every year.
it is made up of:
The ball contains tungsten carbide, known to casue a disease called Fibrosis.
Ink, stored in a, cartridge, also called 'refill', has various dyes and pigments, and other materials like lubricants, surfactants, thickeners and preservatives. These ingredients are dispersed in oleic acid, castor oil, or a sulfonamide plasticizer. Too many chemicals in such a slender item!!!

The cost of making pens is much too high. So don’t throw. Reuse…
