Ugh.

Yeah, they're hard to handle and almost hopeless for small chips. The tip is too big and it's sometimes hard to get them flowing well or they dry out too quickly as you're messing with it.
Nissan sells one just like it and they're common.
Buy some lacquer thinner to clean off the tip before putting it away and to re-wet the tip if it dries out. If you can get a bottle of liquid touchup paint instead of a pen you'd be far better off.
