Review: FWI Nyati & Mianzi

Taiwanese fountain pen line Fine Writing International (FWI) has produced two unique fountain pens exclusively for Endless Pens: buffalo horn pen Nyati and bamboo pen Mianzi. These follow the brand’s Fenestro models, which are longer than usual pens while featuring a 360-degree ink window the body ink

Nyati features a somewhat translucent body that comes in different shades of brown that matches its gold-plated trim. (Unfortunately, it is in one of the few shades that confuse my color-deficient eyes). The ethically sourced buffalo horn body is also well-polished and smooth to the touch, and the one lent to us had a nice dark brown streak on the body.

Mianzi, on the other hand, might not feel like it’s made from bamboo at first until you feel the wood grains at the end of the cap end body. It is as smooth as bamboo would get, sporting a silver trim for a more muted look, with distinct dark brown streaks running down its light brown body.

Nyati presents an interesting pattern on the cap end as well, but Mianzi might trigger trypophobia for some folks.

Both pens come in five Jowo #6 nib options from extra fine to 1.5mm stub, with the FWI logo etched on them.

In case you need to, the pens are quite easy to disassemble. They also have this distinct click when you unscrew the cap, but more on this later on.

So, how do they fare? Here’s what we think:

What’s good

These pens are beautiful up close! If you’re after well-made pens with natural material, these are good choices.

Both pens are long,  but they’re light on the hand. the clear portion is quite big for an ink window but it actually works in proportion to the pens length. Since the nibs are in Jowo #6, swapping nibs would be easy, in case you feel the need to do so.

Speaking of the nibs, both are good writers, never skipping during the entire week of use. But, there’s a small quirk with the nibs, which leads us to…

What’s iffy

Both pens came in EF nibs, but there’s a subtle difference in how they write: Mianzi is wetter than Nyati, with the gold-plated nib laying down lighter colors. This matters if you’re very particular with color accuracy, but this can be easily fixed with a brass sheet.

See if you can check which line was written with what pen with the photo below.

1st line: Mianzi, 2nd line: Nyati, 3rd line: alternating between Mianzi and Nyati. Both inked with Robert Oster Tampa Bay.

For vegan users, there will most likely be an issue with Nyati being a buffalo horn product. Although it was ethically sourced, vegans might want to know more specifics about the acquisition.

There are also a couple of things aside from the length that need getting used to: the clip is quite short, and the screw cap mechanism is quite different, as you need to press the cap deeper to catch the grooves and close the nib.

Noob verdict on the FWI duo

Endless Pens let us borrow these pens to use for a week for this review. This post does not have affiliate links, which means that we don’t earn from any direct purchases if you buy the pens after reading this review.

Nyati and Mianzi is a nice pair of exclusive pens that you’d love to get your hands on if you fancy the feel of natural materials for your pens. It is my first time to try an FWI pen, and there are no complaints about it.

On a personal note, I would choose Mianzi over Nyati. The material simply connects me with the bamboo swords we use in kendo. The smoothness reminds me of that time when we would oil our swords. Too bad we can’t practice in this pandemic. Mianzi is also a wet kind of EF, but if you like a drier EF, you can always get Nyati.

Nyati goes for $169.99 while Mianzi is$128.99 on, who sent let us borrow these pens to use for a week for this review. This post does not  have affiliate links, which means that we don’t earn from any direct purchases if you buy the pens through the links here.
