Its grip has been designed for a more comfortable hold. It includes an integrated eraser which is protected by a clear plastic cone. Ergonomic rubberised grip Sliding metal sleeve Clip design for convenient carrying in pocket With built-in eraser Retractable Mechanical Pencils Category A stick charred by fire could be the world's oldest writing instrument and was first used by early man to mark the surfaces of cave walls. Although charcoal pencils still exist in the art world today, over time a solid pigment core was developed by mixing graphite with a clay binder to produce what is known as the "lead". This is a bit of a misnomer as lead poisoning from pencils was not uncommon and real lead has not been used in writing instruments for a long time. Mechanical pencils developed in late 18th century had a refillable body with a lead-propelling mechanism and extendable core designed to eliminate the constant need for sharpening. Nowadays, Pilot Pen offers a broad range of designs such as retractable button pencils, twist mechanical pencils, mini pencils and "The Shaker" which can be shaken twice to release the exact amount of graphite needed. About Pilot Pilot is a global Japanese brand known for innovation and quality writing instruments. In Australia, Pilot is the brand of choice amongst consumers looking for a smooth writing experience combined with quality and reliability. The Pilot range is extensive, covering premium gold nib fountain pens to everyday ballpoint pens and markers. Most pens are manufactured in Japan, with some also made in France and the US. Innovation is a key to Pilot’s global success. In 2005 Pilot created ‘FriXion’, Australia’s best selling erasable pen. FriXion uses a unique thermo-sensitive gel ink. The friction caused by rubbing the paper generates heat which causes the ink to become invisible. With no damage to the paper, you can erase and instantly re-write over your mistakes.
