"The ballpoint pen I usually use, the writing comfort is good, but the appearance is not formal ..." "I want to have one ballpoint pen with one!" However, considering the frequency of use, the price and the cost of exchanging the core, many people hesitate to buy a luxury ballpoint pen.,ja
"Deff Martirifil Pen Jacket" was born from such troubles.,ja

It is an excellent thing that can be customized to a "luxury writing instrument" with outstanding writing comfort just by attaching your favorite refill (replacement core). In addition, the ballpoint pen refill can be used at a total length of 145mm, a diameter of 6.3mm or less, and a diameter of 2.2 to 2.6 mm at the pen tip, and more than 1,000 types on the market are available in Japan and overseas. There is no need to prepare special parts such as spencers and springs or cut refills.,ja

I worked on "Def Co., Ltd." founded in February 2010. It is a manufacturer that is working on metal -processed products, manufacturing and selling, and has developed mainly on smartphone accessories. Among them, we developed this product using the ideas, design skills, processing technology, etc. cultivated over many years. The material is changed according to the characteristics and strength of the part, and we are particular about the end of the chewy resistance and the finish of the table.,ja

The "Deff Multirifil Pen Jacket" is elaborate to improve the writing comfort. First is the "pen tip". Many of the large amounts of writing instruments have room between the refills and the main body, so when writing, the pen tip shakes and the text blures. On the other hand, this product adopts a "adapter" that can fix the refill so that the pen tip does not move.,ja

In addition, we are particular about the "weight balance" of the pen itself. By designing in the center of the pen and designing the pen tip slightly heavier, it solves the fatigue and difficulty of the hand due to the weight of the pen.,ja

Easy to use, first remove the cap and remove the body from the tip cover. Next, take out the part called "Collet" from the pen tip and attach a refill.,ja,Then, return the collet with refilled to the advanced cover,,ja,Finally, just attach the body.,ja

最後にボディを装着するだけ。

No special tools are needed, and no fine adjustments are required.,ja,I was surprised that the pen tip was firmly fixed even though it was a simple procedure.,ja,It is also a nice point that anyone can use it easily.,ja
シンプルな手順なのにペン先がしっかり固定されて驚きました。
誰でも簡単に使用できるのも嬉しいポイントですね。

The types of products are "aluminum & stainless steel" (Charcoal Black, Sapphire Navy, Turquoise Green, usually sold, 8,000 yen including tax.,ja)And, a flagship model "Titanium & Stainless steel" using titanium alloy, which is also used for artificial bones and spaceships.,ja,One color of Titangray, 12,000 yen including tax,ja,Two types.,ja(チタングレーの１色、税込12,000円)の2種類。

It is a high -quality product that can only be done by a manufacturer that works on metal -processed products.,ja

These commitments were supported by many people, and the crowdfunding site "Makuake" achieved 2993%of 5,986,680 yen for the target amount of 200,000 yen (at the end of January 2023).,ja
