I got this in the mail today, and I thought I might show it here, as some of you may have not seen this type of pen design before. I hadn't until recently, anyway.
Basically it is a dip pen, except it has a collector/feed under the nib. The base of the set comes apart and you fill it with ink, just like an ink well.
In the top part of the base is a reservoir containing little rods of clear nylon. This reservoir rests in the ink, and the rods suck up ink into the reservoir by capillary action.
When you place the pen in the base, the nib nestles into the rods, and capillary action again goes to work, sucking ink into the pens collector.
The base is therefore sealed enough to (hopefully) prevent spills, evaporation, and dust getting into the ink.
I tried the pen by just dipping the tip of the nib into an ink bottle for about ten seconds, and was able to write this page. The ink flow was still going, so I don't know how long you could write before having to recharge the nib in the base. Plenty long enough for stuff that I write, I'm thinking.
A pretty neat design.
