KOKUYO S & T released the stapler "Needleless stapler [Harinax Press] " on October 22nd, which allows five sheets of paper to be stapled without making holes.

The company already sells the stapler "Harinax" series that does not use needles, but this is a type that folds a hole in a document. I was wondering if it would be possible to do that without making a hole this time, so I decided to get it and use it immediately.


◆ Paper sticks just by squeezing!

The main body is available in four colors, blue, green, pink, and white, with pop colors. The manufacturer's suggested retail price is 1,188 yen (tax included).


The shape is not much different from a general stapler. It is a size that fits in one hand of an adult, but it has a heavy weight.


The recommended number of sheets to use is about 5 sheets of copy paper, so first try to close the company materials (4 sheets). When you insert the paper all the way in and lower the lever, you will feel a slight "click". You don't need that strong force, so you can use it while holding it with one hand.


The binding part is uneven like a fastener, but it is hardly noticeable on white paper. The thickness is the same as before binding and it is very smart. Even if you turn the page normally, it sticks firmly. If you do not dare to peel it off, it has sufficient crimping force.




By the way, when you want to peel it off, just flatten the binding part with the back of the pen etc. and it will peel off comfortably. The marks are not so noticeable, so it is beautiful even if you scan or copy. As an office worker, it is a big point to be able to shred as it is.


◆ Why do you stick together?

By the way, why is it possible to close without using a needle? According to the person in charge of development, the Harinax press uses a "press lock type" that uses metal teeth to make irregularities on the paper and crimp it. The fibers of the paper are stretched so that they will not be torn by the wavy teeth, and the paper will stick together by re-hardening with pressure.

The technology itself has been around for a long time, but when developing it as a personal product, it seems that considerable trial and error was carried out, such as prototyping more than 200 teeth and pursuing a structure that efficiently demonstrates the principle of the lever.

◆ How else can it be used?

At the product launch held on the release date, talent Nana Suzuki appeared wearing a "paper dress" made from the same product. It was working fine, but it didn't come off, and the crimping force was transmitted. It depends on the quality of the paper, but it seems that it can be used for work.

This item seems to be a revolution in the stationery world. Once it becomes widespread, the day may come when you will receive a secret memo that was closed by the Harinax Press. In such a case, please rub it open without rushing.
