This Jinhao X750 with Flex nib was only $12.40(!) on AliExpress, though now the price has gone up a bit, it’s about $20 discounted from $30. Even at that price it’s worth checking out.

It’s great so far! The nib has a good “bouncy” soft flex to it; it doesn’t take a ton of pressure to flex, but not a wet noodle.
It was labeled “Fluorescent Black” but it doesn’t actually seem to be fluorescent, though it has a cool starry kinda look from having just a little shimmer evenly distributed around the coating.

It’s not going to beat the Pilot Custom Heritage 912 FA nib, and it’s still a converter so my Jaipur v2 pens with flex nibs win on capacity, but for the price it’s an excellent entry point for a flex nib. I have a flex nib from Osprey that doesn’t flex this much and takes way more pressure.

No flow issues so far with Iroshizuku ink, it did railroad briefly once (in the “Y” on “Yama-budo”), but not much. It also only happened once in two of these note sheets since this was the second time I wrote it all out.

It puts out enough ink to show the sheen in Yama-budo on MD paper which takes a lot, but I’m not sure how it would do with dry inks. Posts from others suggest it may not do well.
