Lanxivi set of 3 Jinhao 100 extra fine nib units (size #6) with black section and silver trim

If you write with a Jinhao 100-style fountain pen often, you’ll eventually want spare nibs. This set of three extra fine nib units is meant for exactly that—quick replacements so you can get back to crisp, fine lines without a big faff.

It’s a small, practical purchase, but it can save you time if your day-to-day writing depends on consistent performance. On paper, these are extra fine nibs from Jinhao’s #6 size range, supplied as three replacement units designed to fit specific pens.

Key takeaways

This is a spare-parts set for specific Jinhao pens, delivered as three extra fine nib units so you don’t have to keep hunting for replacements one at a time. If you already own a compatible Jinhao model and you like extra fine writing, it’s the kind of buy that makes sense—especially if you want continuity for note-taking, journalling, or everyday pen use.

That said, it’s not a universal nib set. If your pen isn’t in the listed compatible range, it may not suit you. Also, because these are extra fine nibs, they’re geared toward sharper, smaller-looking writing, if you prefer a wetter, broader line, you might find it a bit restrictive.

What matters most in day-to-day use

The selling point here is straightforward: replacement is described as easy, by turning the nib section outwards and back. In practical terms, that means fewer tools and less downtime when a nib needs swapping.

One detail worth taking seriously before you start is that you should remove the cartridge or converter before turning the nib section of the nib tip. That’s the sort of “small instruction” that prevents unnecessary mess and stress—so it’s good they’ve called it out.

A quick micro-scenario: imagine you’re halfway through a meeting, you notice your lines have started to look off, you take out the cartridge/converter first, then swap in one of the extra fine nib units. You’re back to tight, controlled writing without waiting for a replacement to arrive.

Compatibility & requirements

This set is described as compatible with Jinhao 100, X350, X850, 9036, 9065, 9016 and 9013. It also states the nib section is size #6.

If you’re buying for the first time, don’t rely on “similar-looking” pens—worth double-checking your exact model number against the list provided. If it’s not one of those models, it’s safer to treat this as a mismatch risk rather than something you can force to work.

Where it shines (and where it might not)

This is strongest for owners who already use Jinhao pens listed in the compatibility notes and who specifically want extra fine lines. Buying three at once also helps if you tend to go through nibs over time, or you simply don’t want to be without a backup.

It may not be the best choice if you’re after a broader or smoother feel, because extra fine nibs are aimed at tighter, more precise writing. And if your pen isn’t in the named compatible set, you could end up with spare parts that don’t fit — a frustrating outcome for what is otherwise a simple, sensible replacement buy.

Should you buy it?

It makes sense to buy this set if you own a compatible Jinhao model from the list and you prefer extra fine writing for everyday tasks like correspondence, journalling, or detailed notes. You’re essentially purchasing continuity: multiple replacement nib units ready when you need them, with a relatively simple swap process described by the manufacturer.

You may want to skip it if you don’t have one of the supported pens, or if you’re not sure you’ll stick with extra fine. In those cases, a wrong-size or wrong-nib choice is more hassle than it should be.
