FRIXION BALL (friction ball) The color disappears when you rub with the rubber on the top of the pen.
How about this? I wrote it on black origami. Its color is colorless. I wonder if colorless is white.
Colorless ink is not sold. Naturally you will make it yourself. It has become.
I bought FRIXION BALL about two years ago. I noticed that I forgot the writing instrument on the road, and I didn’t have a ballpoint pen that I could erase, so I thought it would be useful, so I bought it at Seven-Eleven.
However, I can’t write it if I’m going to use it in a few days. I can’t write at all.
I didn’t find a receipt so I can’t return it.
Well, it’s impossible for a single ballpoint pen to contact the manufacturer’s customer service.
I forgot to put it in the brush as it was.
About two years have passed, and I turned over the brush, and FRIXION BALL came out.
It feels something.
I don’t think I was using it only once, but I was used up only once and I was bored.
I tried it with color before finally throwing it away.
First of all, I tried to write with a slight tilt. This is because the round ball at the tip of the ballpoint pen may not be spinning.
When I tried to write on the notebook, I couldn’t write the letters just by cutting the paper with pressure.
The second thing I tried was to warm the pen shaft with the warm air from the dryer. This is no change.
The third thing I did was try hooking up a shoelace as shown in the image above. This is a countermeasure for when the pen shaft is filled with air and cannot be written.
There is also a method of running on a bicycle spoke (centrifugation).
This was no good either.
The black color has changed to colorless
It can not be helped. I thought about throwing it away.
Suddenly, I read a note on the FRIXION BALL itself.
■ Do not use for anything other than writing. (Well so)
■ Avoid writing with the pen tip above the horizontal, and be sure to store the pen tip after use (because if you write above the horizontal, air will enter and you will not be able to write).
■Do not leave it under high temperature. When the temperature exceeds 60 ° C, the ink becomes colorless.
This is it! Speaking of which, I bought it in midsummer. I remembered that I left it in my car the day I bought it.
That was it. I immediately searched for black origami and wrote it. Colorless.
It was good not to complain to the manufacturer. It was a shame.
Therefore, it can be colorless if left at a temperature of 60 ° C or higher.
I bought a spare core because it is not available in colorless
The writing color is not so good because of the special ink.
I usually use JETSTREAM 0.5mm, which has good writing quality.
