Gakken Stayful will release the official stationery series of the mystery magazine "Monthly Mu" in February.
Monthly Mu is a "super mystery magazine" that focuses on the mysteries and wonders of the world, including UFOs and unidentified animals, paranormal phenomena, psychic powers, and secret stories of ancient civilization and history. It is a longevity magazine that was first published in 1979 and exceeded 400 issues in 2014.
The lineup to be released this time is 6 types that are packed with Mu's world view in every detail. The A5 notebook and ring memo are designed so that you can record them as soon as you encounter a paranormal phenomenon.
There are also A4 files whose designs change depending on how the documents are taken in and out, and block memos that show a "surprise" when they are used up.
In addition, the can badge, which is a proof of the "Mu Survey Team," has a command hidden from the editor-in-chief on the mount. Every item seems to give a little stimulus to everyday life.
