Does it have a refillable reservoir? If so, that's a great bargain if you like the way it writes!
Part of what spurred me to try this experiment is the feeling that the quality of the Uni-Ball lineup has been dropping, including the Deluxe. I still have some 10+ year old Uni-Balls (matte black plastic, not sure the real model name) that are better writers than recently purchased Deluxe modules. A true shame :(
No, plastic cartridges, but you can get a refillable cartridge.
I was worried it would be crap, because who makes a good fountain pen for $5, right? But no, it's sturdy and serviceable. You wouldn't write wedding invitations with it, but for day to day handwriting it's fine. (Daiso is a Japanese "dollar store", and everything in there is about $1.50, so $5 is high-end there, eh?)
I know what you mean about Uni-Ball's quality. I had some of the old black ones from my dad (it was his favorite pen as well) and it does feel like the new silver ones aren't quite the same, eh?
