Post Post (the English name is Post-it, which is a registered trademark of 3M Company) is one of the epoch-making brands created by 3M Company (from the United States), a world-wide top 500 innovative enterprise. It has changed the communication between people. way to make life and work easier and more fun. Post messages or matters to conspicuous places to be reliable personal memorandum notes. Write the message on and post it in a conspicuous place to convey or leave a message, which is easy.

The real inventor of the report was Dr. Spencer Silver of 3M Company, and it was indeed his colleague Dr. Art Fry who could carry forward and be widely used.

In 1968, Dr. Spencer Silver, a 3M scientist, originally wanted to invent a super strong adhesive, but after several months of research, what he got was the exact opposite of what he expected. This adhesive can be tear off. Dr. Spencer Silver marketed his very unique, simple removal or re-addressing patch to other 3M scientists, trying to work together to find some application methods. However, it was time for his colleague Art Fry to find out the actual application before the patch was developed.

In 1974, 3M scientist Art Fry attended church service. When singing in the choir, he was accustomed to putting a note in the songbook as a sign, and the bookmark kept slipping. He could not quickly find the correct number of pages in the collection. I feel annoyed when I turn the wrong collection of poems. So he thought that the bookmark should have a light sticky effect, and also remembered Dr. Silver's paste, and he thought that if there was a kind of glue: "It's a bit sticky but not too sticky, it can be pasted on the paper strip, and it can be tear it repeatedly. It would be perfect if you stick it without destroying the paper! "So, he thought of using this patch to make re-stick note paper. Nowadays, the whole world is praising his small project: posting notes for news.
