Asvine V800 Review: A Vacuum-Filler That Should Not Be This Affordable

Introduction

Every so often a pen arrives that makes you recheck the price tag. The Asvine V800 is a vacuum-filling fountain pen with a large number 8 steel nib, a translucent blue and brown acrylic body, and a price that sits comfortably under $50. That puts it in territory usually occupied by entry-level cartridge converters, not big vacuum fillers, and it raises an obvious question: is this a genuine gateway into vac-fill territory, or a cut-rate imitation?

After filling it, cleaning it, and writing with it in one continuous session, the short answer is that it is a very good pen with a couple of quirks worth knowing about before you buy.

What Is the Asvine V800?

Asvine was founded in 2005 in China. The company’s own story describes a founder named John, a fountain pen enthusiast who started making one-off pens and steadily grew his production into larger, more capable factories. Whatever the full truth of that history, the signal is clear: Asvine positions itself as an ongoing, innovative pen maker rather than a clone shop.

The V800 makes that point on its own. In the box, alongside the pen, you get a wrench and spare valves, TWSBI style. That is a statement about longevity. It tells you this is a pen meant to be maintained, greased, and kept for years, not a disposable. Instructions are included too, along with sensible care advice: never clean the pen with alcohol, avoid carbon or waterproof inks that can clog the feed, and screw the blind cap fully when writing.

Out of the box the pen is immediately striking. The body is translucent acrylic, with blue dominating and only a hint of brown near the back of the barrel. The clip is a Pilot Custom 823 style, the hardware is listed as stainless, and the cap band, while it feels slightly plasticky, sits flush with no sharp edges anywhere. The vac-fill piston action is excellent, with a satisfying snap you can actually hear.

One thing to set expectations on: this pen does not appear to have a sealing valve the way the Custom 823 does, so the cap does not vent the same way. It is also not a lean pen. At roughly 15 mm in diameter and about 33 g, it is a chunky pen, closer to a Montblanc 149 in presence than to the slimmer 823.

Writing Performance

The review unit came with a fine nib, one of four options: extra fine, fine, medium, and a 1.1 stub. The fine writes like a western or European fine, which matters if you are used to Japanese-style fines.

On Clairefontaine paper, the pen is smooth and precise. Ink flow is generous, as you would expect from a big nib, and the fine line has genuine character: slight pooling on strokes, shading in the ink, and an edge sensitivity that runs fat to thin depending on angle. It produces a lovely scribing noise on the page.

To be fully honest, freshly inked it is not flawless. Here and there the flow lets up for a moment, which is why the first impression lands around a B plus. This is normal for a pen that has just been filled and put straight to work; the feed needs time to fully saturate. After more use, that inconsistency should settle.

Fit, Finish, and Hardware

The nib is steel and, as far as anyone can tell, made in house. That is a genuine distinguishing feature. Very few affordable pen brands make their own nibs, but most Chinese brands do, and it changes how you evaluate the pen. You are getting a complete, coherent product rather than a body wrapped around a generic Bock or Schmidt unit.

The number 8 nib is large and attractive, and it delivers the juicy flow big nibs are known for. The vac-fill system and the nib both come from one company, which gives the whole package a satisfying integrity.

Two cautions. The clip is very tight, so think twice before sliding it onto a precious journal cover you care about. And the cap band’s stainless claim is hard to verify; it feels less metallic than the rest of the hardware. Neither is a dealbreaker, but both are worth knowing.

Should You Buy the Asvine V800?

If you have ever been curious about vacuum fillers but hesitated at the price of a Pilot Custom 823, this is the obvious entry point. Many people sample the vac-fill idea before committing to the expensive version, and at under $50 the V800 is even cheaper than TWSBI’s Vac 700R while offering a much larger nib.

The included wrench and valves reinforce the value case. This is not a throwaway pen. It is designed to be serviced, and the tools to do it are in the box.

Buy it if you want a big, handsome, high-capacity writer with a genuinely in-house nib and do not mind a thick pen in the hand. Skip it if you prefer slim pens, need a sealing shutoff valve, or demand perfectly consistent flow from the very first page. For everyone else, this is one of the easiest recommendations in affordable fountain pens right now.

Conclusion

The Asvine V800 proves that a vacuum filler does not need to cost four or five times more to write beautifully. It has a superb piston action, an attractive translucent body, a large characterful steel nib, and a level of serviceability that most pens at any price never offer. The fine nib needs a little time to settle, the clip is aggressive, and the cap band may not be fully stainless, but none of that changes the core verdict: this is a very well-made pen at a price that is hard to argue with.
