Bunsen|Soft fountain pen
A fountain pen with a brass body wrapped in deerskin, making it soft to the touch.
The weight of the brass and the soft texture of the deerskin leather fit perfectly in the handle.
The joy of using it
This is an item that allows you to enjoy the unique aging process that only brass and natural leather can provide. It is a writing instrument that you will grow to love more and more with each use, and that is in tune with the feelings of its owner.

Pen tip
This pen uses a steel nib (pen tip) from a long-established German brand. Basically, you can use it for a long time with proper maintenance, but if it does get damaged, we will replace the nib. *There is a fee for this service.

Game Leather
The material used is made from upcycled deer hides, which are normally exterminated as pests. This is a material that is grown by nature and will not go to waste.

Machined brass
The part that touches the hand is made of brass, and the part that wraps the leather is made of aluminum. The materials are chosen so that the center of gravity is toward the tip of the pen. We are working with a metal processing company in Kyoto that specializes in precision machining.
