Archeological finds in ruins Pompeii include bronze variants of writing pens, however they have received wide distribution only by the end of XVIII century. After a century pens with a capillary system, or simply fountain pens, were invented by L.E. Waterman, a New York seller of writing goods.

Egyptians started to use images in their compositions. Thin reed brushes or feathers were used to make inscriptions on rolls of papyrus. 1300 B.C. Romans used metal pens to write on thin sheets of wax put on wooden bars. Writings were erased by the other end of the pen. Middle Ages. Anglo-Saxons began to use bars filled with wax apart from parchment. They wrote with metal or bone pens, one end of which was sharpened and the other was used for deleting. 600-1800 A.D. Europeans found out that the use of sharpened pens changed the style of writing (handwriting). First they used only capital letters, but later on they began to use small letters to increase speed of writing. Quill pen (goose feather) that for the first time appeared in Seville, Spain, was used as a writing instrument from 600 to 1800 A.D. 1790ies. Independently the slate pencil was invented in France and Australia. 1800-1850ies. The metal fountain pen was patented in 1803, but the patent was not used in commercial purposes. Steel pens were widely adopted in 1830ies. In 19th century metal pens completely replaced pens from goose feathers.

In one of the large store departments in New York more than 10,000 ballpoint pens were sold during a lunch on October, 29 1945. In 1953 the first inexpensive ball pens appeared, when French baron Bich of BIC Co, engaged in manufacturing of ballpoint pens, managed to improve the technological process and lowered considerably manufacturing expenses. Bic pens were very cheap and soon became extremely popular. In 1960 the felt-tip pen was invented in Japan. Soon felt-tip pens appeared on the American market and grasped it. Rollerball pens appeared in the beginning of 1980ies. They had a moving ball and could use liquid ink that allowed to write smoother line on paper.
