If you’ve already experienced Pilot cartridge/converter pens, then this is a good time to try piston vacuum fillers. The Pilot Custom 823 is a great option, especially if you’re someone who does a lot of writing and needs a huge ink reservoir. This pen can store up to 2.55 ml. of ink and has a translucent barrel enabling you to see how much you still have before you need to refill. It’s a workhorse with an understated design, but it comes with a 14K gold nib that allows you a smooth and well-balanced writing experience.

We have for sale a pre-owned Pilot Custom 823 Amber with a juicy B nib. It has minimal signs of use and comes as a gift set complete with its box, papers, and ink bottle.
