I didn't flush the pen, just popped in the cartridge. As soon as the feed was saturated, the pen wrote really well. I was really impressed and really pleased with the performance of the nib. It is a nice medium, even for what a Japanese nib (assuming it is Japanese made, at least). The ink flow is nice and steady. What is interesting about either the ink or the nib is that the ink dried almost instantly once it hit the page, even on Rhodia. It was like writing with a fine liner pen. The nib also had no line variation whatsoever - hard as a nail. But it flows well and writes well, which is the whole point of the pen!
This is where the pen differs a little from the Pilot Petit1 fountain pen. The Pilot pen has a more secure posting mechanism for the lid. This lid has to be pushed on very hard to stay in place, and even then, when it rubs on the web of my thumb, it can wiggle off. If it isn't posted deeply enough, it could just fall off. It's a small pen so if you have larger hands, it may be difficult to write with without being able to post it. For me, I can manage with it unposted. Posted, unless you can keep it securely posted, it'll probably be too small.
PROS & CONS
This pen is pretty much the same as the Pilot Petit1 fountain pen. Given the price point being similar to that of the Petit1, and that they have the same features aside from the Petit1 having a fine nib and the Snowhite having a medium nib, they're about the same. They have similar colour options and sizes. If you prefer a medium nib, then you could always try out the Snowhite instead of the Petit1. Otherwise, the Petit1 is easier to get.
