Pen manufacturers used to make demonstrators for distributors as a sample that showcases the inner workings of fountain pens. These days, they are considered a design decision and are offered to the public for them to also enjoy the engineering and craftsmanship of their writing instruments. 

The Pilot Custom 823 Transparent is no different, and is honestly one of the most reliable, gold-nibbed pens of the brand. Its clear barrel showcases its vacuum-filling mechanism and lets you know how much ink you still have—which is a lot at a maximum 2.5 ml. This is a pen that will always be in your rotation simply because it does the job well. That it’s beautifully designed is almost just a plus. 

We have for sale a brand new Pilot Custom 823 Transparent with an M nib in 14-karat gold. It comes complete with its box, papers, and ink bottle.
