While this pen still has a traditional joint for the section, it is filled by pulling out a plug in the feed. The plug stays attached by long twisted wires. It is reminiscent of the Hicks Sackett in how the parts remain attached during filling, and also similar to the Rider with its feed removal design. This is a very “finger friendly” dropper fill system. The plug should be ink free, so unlike a standard dropper filler, or the Hicks Sackett or Parker Jointless, or others, you never need to touch any inky parts to open or close the pen. They claim you can also adjust the ink flow with the plug, but current Swan fans don’t agree.
