Biodegradable Ballpoint Pens – I’m crazy about these! I have a metric ton of plastic-barreled pens all over my office that seem to materialize from nowhere and never write well. I need to have pens around but I’m not crazy about bringing yet more plastic junk into my house. Paper Mate comes to the rescue with a biodegradable pen that will disintegrate in your backyard compost bin when it outlives its usefulness. Brilliant!
