I'm currently using this converter with the AS Manhattaner's pen I purchased.
The converter fits well, and sits nicely in the pen. I write quite a lot, and
the the reservoir lasts me about two days each refill. Though the first time I
used the converter I did accidentally unscrew the reservoir from the rest of the
converter when I was trying to refill. When you refill this one, remember to
hold onto the metal bit and the plastic bit so that the metal doesn't unscrew
from the plastic by accident like I did. The design is simple, just twist the
end to move the plunger up and down the reservoir to create a suction to push or
pull the ink.
Leaky! Use with Sailor Clear Candy and I spend more time washing up from this
converter than I do using the pen. Rather poorly constructed. Have a Lamy
Safari with converter, have no issues at all. Going back to cartridges for this
