Speaking of pilot's hit products, the writing tool "friction" that "disappears when rubbed". Among them, the multi-colored ballpoint pen "Frixion Ball 4" is convenient because it can be used properly with one, but when writing an address or signing a document, you have to switch to a normal ballpoint pen.


However, according to an acquaintance who loves stationery, there are items that can create original friction that meets such needs. I tried immediately.

The item is the "ballpoint pen refill adapter (PF-01)" sold by Fukushima Seisakusho's product label "UNUS PRODUCT SERVICE." The package says "PILOT friction ball 3 and 4 refill compatible model", but it seems that it is not a joint development with the manufacturer.


Since the standards for replacement cores sold by stationery manufacturers are different, it is basic to use them with the same manufacturer's body. However, by using this adapter, it will be possible to install refills from other companies (check for compatible products).


This time I used "Frixion Ball 4" champagne gold. Of the 0.5mm black, blue, red, and green colors that are pre-installed, I'd like to change the green that I rarely use to 0.7mm black, which is my personal favorite "Jet Stream."



All you have to do is insert the replacement core into the adapter and push it firmly into the main body from which the original refill was removed.






Furthermore, if you replace the blue with "Frixion Blue Black 0.38" for your notebook, you will have the author's "original friction that you can do your job with this one"!




By the way, replacement rubber for erasing is also on sale, so if you replace it with your favorite color, the original feeling will increase.




Two adapters are available for 725 yen (tax included) and can be purchased at Amazon.co.jp. It's spring when you want to make new stationery, but how about customizing it like this?
