What's great about Treehugger is that I don't feel they are selling pens but rather they are selling the idea that every little thing that we do counts, starting with just a pen. You do not need to go out of your way to do your part in helping out. You can live life just the way you always have and still make a big difference. Buy a pen, save the trees! Treehugger products are made available at your favorite bookstores and establishments.
