How long the ink lasts in your Pilot Metropolitan Fountain Pen can really depend on how often you're writing and whether you're using a cartridge or bottled ink.

Here's the deal: this pen usually comes with black ink cartridges and a converter. According to the manufacturer, this setup is so you can easily toss in a cartridge or use the converter if you want to dive into bottled inks.

Now, about the ink's lifespan: cartridges are pretty straightforward and last a decent amount of time if you're writing regularly. But once they're empty, you'll need a new one, and they do run out faster because of their limited capacity.

If you're using the converter, some folks in our research pointed out that it's a neat feature for tapping into bottled inks, but it doesn't hold a ton. If you're someone who writes a lot, you might find yourself refilling more than you'd like. There's a slightly bigger converter, the Pilot CON-40, you can buy separately. It holds a tad more, which could help stretch out those refill intervals.

One thing to keep in mind—the converter is specifically designed for Pilot pens. So, if you have a range of pens, you're a bit stuck with this one type when it comes to converters.

Overall, though, people are generally happy with how the Pilot Metropolitan performs. Switching between cartridges and bottled ink is a big plus whether you’re new to fountain pens or a long-time fan.

With the variety, you won't run out of ink forever, but the options really give you the flexibility for whatever writing vibe you’re going for.

The Pilot Metropolitan Fountain Pen uses specific ink cartridges called Pilot Namiki IC100 cartridges. They're designed just for Pilot pens, ensuring smooth ink flow and consistent writing.

If you're into bottled ink instead of cartridges, the Metropolitan also includes a converter, so you can try out any fountain pen ink you fancy.

Our research suggests that people appreciate having both options. Cartridges are quick and easy for those who like keeping it simple, whereas the converter gives you the chance to explore different ink colors and types.

The Pilot Namiki cartridges are known for their reliability and vibrant colors, and they're pretty easy to swap out. So, you get a hassle-free writing experience.

Using the converter is just a matter of dipping the nib into the ink bottle and twisting the converter to fill the pen. Some fountain pen lovers find this process hands-on and satisfying.

While there are plenty of other inks you could try, sticking with Pilot's cartridges or using their converter generally provides the best compatibility and performance.

So, in short, the Pilot Metropolitan is flexible with its ink options. You can use the cartridges for ease, or experiment with bottled ink using the converter. This versatility is why it's popular among both beginners and seasoned fountain pen fans.

The Pilot Metropolitan fountain pen is pretty well-known for having a fine nib that's usually smooth to write with. From what the manufacturer says and what we've gathered from reviews, it generally doesn't scratch much, which is ideal if you're into fluid handwriting.

Some folks, however, do mention that the nib can feel a bit scratchy sometimes. According to our research, this can depend on things like the paper you're using or your writing style. Interestingly, some people actually like that slight scratchiness because it gives them a more nostalgic, traditional fountain pen feel.

But if you're used to really smooth modern pens, this might be something to think about.

The fine nib on this pen is definitely a highlight. It creates clean, precise lines, perfect if you like neat handwriting. People often note that it’s impressively smooth for its price, making it a great choice if you're just starting with fountain pens.

If you do notice some scratchiness, pairing the pen with fountain pen-friendly paper might help a lot. Also, using the Pilot ink cartridges that come with the pen is a good idea since they're specifically made for it, which can help with ink flow.

In summary, while a bit of scratchiness is mentioned in some feedback, many find the Pilot Metropolitan to write smoothly and satisfactorily. Whether it feels scratchy or smooth can really depend on personal preference and how you use it.

Overall, it's a popular pick, especially for beginners getting into fountain pens.
