The creators of the Both Sides Post-It came across some alarming research that stated that one person might be responsible for the consumption of 237 trees in his lifetime, all to meet his paper needs. This small product has been conceived to make a significant difference to future statistics by reducing the use and disposal of adhesive memos by half.
Jeon Chang Dae, Kim Hye Su and Shin Min Kyung have proposed a very small modification to the standard compact notepad: a single slice. The smile-shaped cut in the top of the paper allows the rounded tab to be folded back so that some part of the glue strip can face the other way. The Both Sides Post-It can thus bear two separate consecutive messages stuck to different surfaces.
