Pilot Kakuno vs Metropolitan vs Prera (2026): Which Should You Buy?
Kakuno, Metropolitan, and Prera write more alike than their prices suggest. The useful differences are in the body: Kakuno is light and cheap, Metropolitan is heavy and made of brass, and Prera is compact with a notably firm snap cap.
For most first-time buyers, start with Kakuno. Choose Metropolitan if you already know you like a heavier pen. Pay for Prera when compact size and cap action matter to you; do not pay more expecting an automatically smoother nib.
Specifications that change the decision
| Model | Typical US price | Body / weight | Grip | Ink |
|---|---|---|---|---|
| Pilot Kakuno | $12-18 | Plastic; About 11 g | Shaped grip with finger guides | Pilot cartridge; CON-40 or CON-70 |
| Pilot Metropolitan | $15-20 | Brass barrel; About 26 g | Round grip with a noticeable step | Pilot cartridge; CON-40 |
| Pilot Prera | $33-37 | Plastic; About 15 g | Round grip; compact body | Pilot cartridge; CON-40 |
Prices are typical US ranges from the site catalog at the July 2026 update. Color, nib, and bundle prices vary.
The nib is not the main difference
These pens use Pilot steel nibs of a similar size and character. A Metropolitan can write better than a particular Prera, or the reverse, because individual nibs vary. Extra-fine and fine nibs also give more paper feedback than medium nibs. Compare the bodies first; choose nib width from your handwriting and paper.
When a Kakuno upgrade is worth paying for
Keep the Kakuno if it is comfortable and your only complaint is that it feels inexpensive. Metropolitan and Prera use closely related Pilot steel nibs, so a higher price does not guarantee a smoother line.
Change pens when the body gets in your way. Metropolitan suits writers who want brass weight and a restrained office look. Prera is the better move when you want a shorter body and a firmer snap cap. If neither change solves a problem you notice while writing, buy ink or paper instead.

FAQ
Which is best for a first fountain pen: Kakuno, Metropolitan, or Prera?
Kakuno is the simplest default because it is light and inexpensive. Metropolitan suits buyers who prefer a heavier brass body. Prera earns its higher price through its compact body and cap, not a clearly superior nib.
Is Pilot Prera smoother than Kakuno or Metropolitan?
Do not assume so. All three use small Pilot steel nibs with similar writing characteristics. Nib size, ink, paper, and normal unit-to-unit variation can matter more than the model name.
Which model holds the most ink?
Kakuno can accept the larger Pilot CON-70 converter. Metropolitan and Prera are generally limited to smaller Pilot converters, although all three can use Pilot cartridges.
Should I upgrade if my Kakuno still writes well?
Only if you want a different body. Metropolitan adds brass weight and a more conventional look; Prera adds a compact body and snap cap. Neither is a guaranteed nib upgrade.
