Pilot Tank

Today's pen of interest: The pilot tank. It uses the same nib as the pilot 78G, same feed too.

of course it writes as well as that legendary pen but it comes with a larger capacity.

The interesting part of this pen, it is an Eyedropper. One observation about pilot tank as an eyedropper: it doesn't burp at temperature difference and low volume. And its not due to the feed. The key is that sponge like material at its end.

Looks like pilot did have a quick fix for ED less that troublesome VAC type contraption that some other Japanese maker invented.

and if you want to drastically increase its volume, just remove that sponge like material. It does pose a problem when cleaning the pen with that device. cleaning can take.....forever :p

Of course, if you really want to use a converter, it can be converted to a converter based pen.

 1) it is a dropper type. the volume is quite big already, but it can be stretched further. there is a black plastic thing in the body of the pen, remove it, and you get roughly 2.5cm more of the body's volume. it doesn't leak even if you remove it since the plastic does not have any holes.

2). If you want it to use a con20 or con50(con70's diameter is too big, or you want to use a cartridge, just remove that rubber thing from the pen body. the converter can be inserted. there is no leakages as well.
