The overfeed extends the width and range of lines you can draw. It rests above the nib, stores more ink between the nib and overfeed, and lets you draw wider lines for a longer time. Read more about our overfeeds.
You can replace the overfeed with a spacer when you don't want to use the overfeed. Slip overfeeds and spacers in and out.
About the reservoir
You can double the volume of ink or paint stored in the pen by removing the reservoir and filling the body. The reservoir provides a double wall of protection, which might be what you want, but you can carry more volume without the reservoir.
Note: This pen is slightly more expensive than other large nib Pump Pens because of the higher cost for the Brause Rose nib.
Feed flow rate
This pen ships with the standard feed flow, which works with most popular drawing inks and paints. You can order the rich flow feed, which is designed for especially thick inks and paints, such as traditional India ink and acrylic paint. We suggest you try the standard flow feed first, and if that doesn't work, step up to the rich flow feed.
Other nibs you can use
Slip in the Zebra Manga G, our Sketch nibs, most other Brause nibs, some Osmiroid nibs, and selected Hunt nibs including the 22B, 56 and 101
