The new Post-it Super sticky note has a greater adhesive force than the traditional Post-it notes. To demonstrate how sticky they really are they have created a direct mailing. They wrote the address on a Super Sticky instead of on the envelope itself. This is the best proof of the quality of these Post-it’s, because when you mail a letter it goes through a lot of stuff before it reaches it’s recipient. Besides being a mailing, it was also a quality test, because 99% of the letters arrived they could say the quality was more than sufficient. Above the picture of the envelope you can read the letter they’ve sent to potential customers.
