The first time I saw the TWSBI ink well, I was totally oblivious to the the additional functionality that it was hiding under that black cap and silver metal spacer that you see above. One quick thing before I explain how it works, it is important to note that the ink well also comes with several different color choices for the metal band. As you can see from the photo above, the ink well when used with just the black metal cap acts as any normal ink well, and has a plastic cone in the center to help get the ink into your fountain pen when you are refilling it.
The really cool part though comes when you place the metal spacer on the neck of the bottle. It has a tiny hole in the top which is connected to the slim pipe that you saw in the previous picture. This allows you to remove the nib from the pen, and place the pen onto that tiny hole so you can fill the pen while bypassing the nib and feed.
Filling the pen using the metal spacer makes for a much cleaner, neater, and faster filling experience. To me this is a great solution that completely gave me the ability to now keep this at my desk at work. Before I never would have thought about filling a pen at work because of the potential for mess and need for cleaning up the nib. This option only requires a tiny wipe of maybe one small drop of ink that could get away from you, not to mention that the bottle itself just looks pretty awesome.
Having both the TWSBI 540 Demonstrator Fountain Pen and the TWSBI Diamond 540 Ink Well takes the fountain pen writing experience to a new level. The design, construction, functionalyty, and the way they match so nicely makes this something that would look fantastic on any desk and it is just plain fun to use.
