Refill Pen Jacket (Aluminum / Titanium Series)

Japanese Designer Brand, Update Your Beloved Ball-Pen

There's a mounting clip inside the Refill Pen Jacket, which can hold the pen nib tightly. The design aims to reduce

shaking of pen nib and improve smoothness and stability while writing. While changing pen lead, you only need to 

unscrew the mounting clip from the pen holder, which is pretty easy. 

The pen cover is designed to be cylindrical and has a gradient from thick to thin to improve  holding comfort. The 

holding grip and the mounting clip is made of SUS304 stainless steel, and the pen body and the pen cap are made 

of aluminum (A6063), overall weight only 28.4g. 

Well-balanced counter weight, improved writing comfort
The reason why ball-pens can't be written comfortably is because of the weight balance while holding rather than 

overall weight, and writing comfort usually comes from the counter weight, which the pen head is slightly heavier 

than the pen body. 

Extreme Craftsmanship with High Quality Material
DeFF is a Japanese manufacturer specialized in planning, producing, and selling of metalworking products. We strive 

to ensure that each product we make can be perfectly presented. While designing, they not only look nice but also

anti-corrosion ; and the pen grip is made of PVD polished SUS304 stainless steel, which makes the pen perfectly

weighted and have an overall beauty. 

Titanium / Stainless Steel Version（Titanium Grey）
Titanium metal is very hard to process and requires special method different from steel and aluminum. We now 

reveal a platinum version adapting all the aluminum parts to titanium material. Titanium is also called Ti64, a special  

alloy that is much stronger than pure titanium. It is so highly reliable that is even used for artificial joints for medical  

use, and also nuclear power, aerospace industry, and so on.

For Multiple Necessities
Ball-pens can be adopted to personal or formal occasions and so on. Many people yearn for taking out a high- 

quality pen from their suit pocket in front of their customers, but usually fail to take their first step  because of 

its high price and pen leads cost. 

But Japanese ball-pens are still popular among people who care a lot about writing utensils. They do perfect job 

on writing despite their fairly low cost. And with our Refill Pen Jacket, it not only levels up the appearance of the 

pen, bot also improve the comfort while writing.
