I was tired of constantly having to dip my old pen in the ink reservoir whenever I needed to apply ink to paper. I recalled seeing something like this being used by a co-worker of mine so I decided to get a box for myself. I pulled one of the devices from the box and was amazed that I was able to apply ink directly to paper without having to dip a quill in ink or go through the messy ordeal of filling a fountain pen! And what an amazing price! I have a feeling I will not only be using these to apply ink to paper but also to remind myself of important events by applying ink directly to the back of my left hand! What an amazing little device!
