Artificial stains are indispensable for posting posters and other items on walls. Recently, tape that can be removed cleanly has been introduced, but in the end, "sticking it in with a needle" is the most stable.

However, I am concerned about making a hole in the wall. For such people, we recommend "Ninja Pin," a thumbtack that leaves no noticeable marks.


The price is 1,100 yen (tax included) for a pack of 15. They are available at stationery stores and web stores.


The push portion is a simple cylinder. Colors include clear, white, and black. The one in the image is clear.

The distinctive feature is the pin. The tip is V-shaped.



This makes the pin less noticeable when it is inserted and removed from the wall. If the pin is inserted in line with the unevenness of the wallpaper, it will be less noticeable. The force required to insert and remove the pin is about the same as that of a normal thumbtack.





The name "Ninja" is a clever reference to the inconspicuous nature of this product. How about using it for a little spring makeover?
