Penol is a Danish developed and Danish designed product. The products are primarily developed for the Scandinavian markets. In a modern society, the environmental issues are often at the top of the agenda. Penol products reflect this. Penol pencils are made of government controlled replanted plantation wood. PVC, when burned, has a negative effect on the environment. As Penol do not wish to contribute to toxic emissions, Penol packaging is made from 100% recycled paper material, or from PET, a plastic material with almost no negative effects on the environment.

All Penol marking pens are without xylene, most of the marking pens can be refilled with ink, and nibs can be replaced when they are worn out. Penol A/S are constantly developing their products in order to have a top quality product line with a minimum of environmental influence.

Penol children's fibertip pens are manufactured with ventilated safety caps and welded backends that cannot be removed. The Penol children's products are among the most childproof products on the market - a position Penol constantly strives to improve. The Penol children's fibertip pens are fitted with a large ink reserve, with high quality ink. This provides the pen with long lasting excellent colouring capabilities - and therefore better value for the children.
