Improved model has been shipped since Sep. 2013. Here are the improved points:
1. The ink used for the surface of body has been chemically-improved to avoid the slipping out of your hand.
2. To prevent the Multiliner from “dry-up” problem, we reduced the size of air chamber by adopting double cap.
3. We changed Multiliner’s reservoir to integrated type to prevent ink from leaking.
* Inks and nibs remain the same.
* Be sure to close the cap tightly until you hear a click.
