Inspired by the great inventor Nikola Tesla's experiments with static electricity, these reinvented sticky notes will stick to almost any smooth surface. How? They do it through the power of a unique patented technology called statically charged polypropylene film. Better yet, they leave behind no residue and can be moved and replaced. The writable side is reusable and wipeable, too. The coloured front side serves as a writable surface for pens, pencils, or marker, while the shiny back side is like a dry erasable whiteboard that you can use time and again.

We don't recommend using gel pens, because the ink takes time to dry and tends to smear. For the dry erasable back, we recommend non-permanent, water-based marker. Alcohol-based markers can damage the surface and are more d
