The fountain pen took over years ago. With the idea that feather wand act like a reservoir of ink, they use it and top up with a quill pen. The idea is to have a storage capacity of the ink in the pen, as one does not need someone to hold a pen dipped in ink every now and then. The main challenges that confronted them were leaked that comes withal metal pen from the pen.
Backing on this idea though, Lewis Waterman decided to try his hand at making fountain pen and sure enough, in 1884, it comes with a decent product, at the best of times. He made a patent on the pen and this is how he became a pioneer for the industry to write.
Today, you will find that the fountain pen that comes in nine different pen sizes. They can be tilted, slanted or straight. The ink composition has also changed quite a bit since these days it is not solely extracted from plants. The ink reservoir is made of rubber material that you press and put in a bottle of ink and when you release it, it is filled with ink.
