Rock Paper Spiral Notebook, Reduce, Reuse, Bicycle (RP301) Rock Paper requires No water whatsoever during production. This is the most revolutionary benefit in the production of Rock Paper. The regular pulp paper industry is the most responsible culprit for the Earth's water pollution. Rock Paper requires no toxic or chemical bleach to render the paper white, as the lime stone used during its production is naturally white. This is yet another revolutionary aspect of Rock Paper. Incidentally, this is one of the main factors why there is no water used during production. Rock Paper is composed of 80% Calcium carbonate and 20% polyethylene, which is a non toxic recyclable and re-usable resin. As such, the paper has no biological properties whatsoever and has no fibers creating an antibacterial surface! For the same reasons as above, the lack of biological properties or fibers, Rock Paper is water resistant. Spill your coffee on your desk? No worries, liquids will wipe off Rock Paper without smearing the ink!
