A stationery that everyone will have used once, "a memo that can be pasted and peeled off (hereinafter referred to as a sticky note)".

I'm pretty forgetful, and I use it so much that I put it on my smartphone, but depending on the manufacturer, is it easy to peel off or the characters are difficult to write? In the first place, why can I re-paste it many times?

I participated in the "Za 3M Seminar" of 3M Japan, which sells the "Post-it" notebook, which is synonymous with sticky notes, and approached the secret. As a special guest, Mr. Masayuki Takabatake, also known as "Stationery King", will also appear!


■ An anecdote that is too famous? Post-it notes born of failure

Post-it notes came from Spencer Silver, who was developing a strong 3M adhesive, who made a "well-made but easy-to-peel" failure. Worldwide sales began in 1981, and sales began in Japan in 1983. Currently, it seems that more than 500 kinds of post-it products are being developed in Japan.


■ Why don't you stick too much?

According to the company, the adhesive used in the product is "spherical". Therefore, when we experimented with the difference in adhesive strength between the spherical glue and the flat glue models, we found that the spherical glue has moderate adhesive strength and is easy to peel off. Anyway, you can do this on a small piece of paper!




■ Do that much !? Stationery King thoroughly explains Post-it's "Sugoi Koro"

Next, Masayuki Takabatake, also known as "Stationery King," appeared as a special guest of this seminar. I can't hide my excitement in front of the living legend, the author of the stationery lover and TV champion generation.


By the way, even though it is a 3M event, Mr. Takahata does not allow any compromise on stationery. On this day, he examined and explained the sticky notes of the six companies from various angles.





According to him, the post-it notes have reached a very high level as a result of examining the three points of "adhesiveness", "writing comfort", and "remaining glue". The maker seemed to be thrilled, and the author, who had nothing to do with 3M, was relieved (by the way, F is 3M).

Post-it products that Mr. Takahata often uses are smart type and index type that fit in a pen case.


He also flew an airplane as a secret trick (?) To enjoy sticky notes!
