Ballpoint Pens and Work

Ballpoint penIt is a must-have for adults. It is an adult essential.

They are important business partners for working people.

Some people pay as much attention to ballpoint pens as they do to clothes and watches, while others just want to write with whatever they can write with.

Am I the only one who thinks it's nice to meet someone who casually uses a classy ballpoint pen at a business meeting or conference?

I believe that people who are mindful of their work tools are people who can do the same for their work.

My favorite is Charleston by Waterman (WATERMAN) of France.

I have been using it for 8 years now, and it is the longest ballpoint pen I have ever used.

I like the simple design and moderate weight. The price is not as good as a 100 yen plastic pen, but I think it is not expensive because it is something I use every day.

However, there is one thing that bothers me about this beloved ballpoint pen. It is.the feel or performance of a penIt is.

The ink is too thin, or too faint, or not enough for me anyway.

I often scribble on my notepad for work, and I always want a smooth writing experience.

I want to use refills from other companies in my favorite ballpoint pen.

Ballpoint pen refills are called refills.

Refills are not interchangeable among manufacturers, as each company uses a different refill format.

In the case of foreign brand ballpoint pens, genuine manufacturer refills are few in variety and expensive. For example, one Waterman pen costs around 1,000 yen.

More than once I wished I could use refills from other companies.

Japan, a leading ballpoint pen country, has many ballpoint pen manufacturers with high technology. There is a wide variety of refills available at reasonable prices.

One of my favorites is Mitsubishi Pencil's JETSTREAM.

The ink, which was originally developed by the company, allows for smooth yet clear writing. It is as if skating on paper.

"If you can use JETSTREAM refills with Waterman ballpoint pens, you can use them with Waterman ballpoint pens. ・・・・

But then I saw on AMAZON that they sell refill adapters for Waterman! And it's made in Japan!

I immediately purchased and installed it and was very satisfied.

Some people mistake Mitsubishi Pencil for Mitsubishi Group, but they are two different companies with completely unrelated capital and history. The founder of Mitsubishi Pencil is Jinroku Masaki, while the founder of Mitsubishi Zaibatsu is Yataro Iwasaki. The famous three diamond-shaped mark is based on the "Mitsuuriko" (three scales) family crest of Mitsubishi Pencil's Masaki family, and was registered as a trademark before Mitsubishi Zaibatsu.
