It is the public's favorite writing experience, showing luxury.




Refill Pen Jacket can use more than 700 refills on the market and support many overseas products, which can be installed without modification.
The unique chup structure ensures that the chup correctly clamps the refill by tightening the upper and lower parts of the refill cover. In this way, the pen can accommodate refills of various shapes.

The refill is installed on the fixing clip, and then the fixing clip is put into the pen tube. There is no need for adjustable gaskets, fixed springs, and no need to modify the refill.



When using a writing tool, I find it difficult to write. Compared with the overall weight, it is a matter of weight balance.
Supported by the central part of the pen, the balance of the slightly heavier tip of the pen is the key point of easy writing.
Aiming at the weight of the pen, which is neither too light nor too heavy, the wonderful part of the texture is just right.
Please note: When wearing the pen cap at the back, the balance will be biased to the center or from the back.
[You can write according to what you think where you think]


Most of the mass-produced writing tools have room in the mating of the refill and the pen body, so the tip of the pen will shake when writing.
In this case, I can't write according to my idea, and the words will be blurred.
This product is a fixed snap, which fastens the refill tightly, making writing easier by preventing shaking.

So far, the pen case alone is about 145mm, which is a general length, but it has also received many "too long" comments.
Therefore, we investigated again to find a length that balances portability and ease of writing, and this time shortened the full length to about 117.5mm.
Please experience the advantages of this length that you can only know when you pick it up.


The pen cap is fixed by a magnet. Every time you remove and put on the pen cap, you will feel a pleasant metal "click" sound.

Like the first version, the main material is A6063 aluminum alloy, which has excellent corrosion resistance and good finish.
The basic model is made of SUS304 stainless steel to manufacture parts that require strength, and there are four colors to choose from.
The special highlight style of the third generation is brass.

On the other hand, brass is easy to scratch because it is very soft, and there are also negative factors of surface changes and weight caused by oxidation, so
Most of them have been replaced with aluminum or plastic, but they are still deeply rooted in popular materials.

Sometimes it may fall down and get scratched. However, even so, it will be engraved on the pen as history.



The pen itself can stand vertically. The oval base has enough weight and is not easy to fall down. Like the pen cap, it has the click of a magnet.
The mirror treatment is available in two colors, black and gold. Please match them according to your preferences and colors.




From formal to private, it meets a variety of needs. Many people will be happy to take out a high-end pen in front of the meeting or guests.
I want to have a pen that doesn't embarrass, but considering the price and the cost of replacing the core, I recommend it to those who can't take this step.
Those who often write and those who are particular about ballpoint pens should also try it.
Especially the domestic ballpoint pen, even if it is 100 yen, there are many excellent ballpoint pens that are comfortable to write.
Please keep your favorite ballpoint pen and enjoy the upgrade of appearance and writing.
