Creative Sticky Notes

In 2003, the company came out with Post-it Brand Super Sticky notes, with a stronger glue that adheres better to vertical and non-smooth surfaces.
Standard Post-it Brand notes have only partial adhesive coating on the back, along one edge. Similar products are used for specialized purposes with full adhesive coating; the US Post Office uses such yellow address labels to forward mail.
The yellow color was chosen by accident; a lab next-door to the Post-it team had scrap yellow paper, which the team initially used.
