"After I'm done, it's perfect!" Colorolio Pebble Eraser Introducing the Colorolio Pebble Eraser! The Perfect Eraser for Every Imperfection. We're all familiar with the usual brick like shapes of erasers. Gray or pallid in color. If one could build a better eraser, what would it look like? We made one which not only looks and feels good in your hand, but is also useful for erasing thin pencil lines or thick streaks. Our Pebble Eraser is much cleaner than the traditional rubber eraser, leaving little residue on your paper with no color transference. The Pebble Eraser feels delightful and natural between your thumb and fingers, as if no other eraser shape could exist. Please know that like most pencil erasers, the Pebble Eraser will not work well on Oil or Wax based mediums. Available in Green, Red, and Yellow, each eraser comes individually packaged. The Colorolio Pebble Eraser; doesn't necessarily mean a perfect world has arrived. But just one Pebble Eraser, carefully applied, inches us ever closer.
