I've been using a Staples eco-friendly notebook (there are more designs in-store) for the past several months, and I'm a huge fan.  I'm the type of person who's pretty skeptical of eco-things, but if it's a good product for a good price, I'll use it.  Its eco-friendliness comes from the fact that it was made using sugarcane plant fiber waste, which is cool because (a) they're using a part of the product that's generally not very useful, and (b) it has something to do with sugar, of which I'm also a huge fan.  If only it was edible. #products
