TCM pencils are made from recycled newspaper and recycled paper, these pencils are completely tree-free (no wood has been used in making the pencils unlike the conventional which are available in the market). This is the greatest way to make your children understand the importance of trees & natural resources.

In addition, they are great gifts for friends, for your loved ones and for corporate giveaways. Also perfect as an office stationery item. Just imagine a small shift from conventional thought we can collectively make a great impact in saving a lot of trees and thus giving helping hand in saving out PLANET.
