PET Branded Promotional Post It Notes Arrow Shaped 50mm X 35mm

Sticky notes are small, rectangular pieces of paper with a sticky adhesive on one side. They are often used to jot down notes, reminders, or ideas and then stick them to a surface such as a desk, computer monitor, or wall. Sticky notes are a popular tool for organization, brainstorming, and communication.

Sticky notes were invented by Spencer Silver, a chemist at 3M, in the late 1960s. Silver was attempting to develop a stronger adhesive, but instead, he created a low-tack adhesive that would stick to surfaces but could be easily removed without leaving residue. However, it wasn't until 1977 that his colleague Art Fry came up with the idea of using the adhesive to create a reusable bookmark, which eventually evolved into the modern sticky note.

Today, sticky notes are available in a variety of colors, shapes, and sizes, and have become a ubiquitous tool in offices, classrooms, and homes around the world. They are also known by various names, including Post-its (a trademarked term by 3M), repositionable notes, and memo pads.
