today i bought an "eco-friendly" notebook.
it's called a rock notebook. (^_^)V
the pages are made of 80% rock and 20% plastic.
the technology behind that i have yet to research. (^_^")
anyways, it is considered "eco-friendly" by it's makers because it lessens the trees that are cut down to be used as paper. (^_^)
hehehe~
not sure about this (^_^")
i just read it from the packaging. (^_^)V
