What it is
Pocket eyedropper, ~86mm capped and ~120mm posted, that takes over 2ml of ink — more than most full-size cartridge/converter pens. Sold in dozens of colourways across two generations (Pearl and Candy series in gen 2).

Dimensions mined from retailer listings and cross-checked across stores — approximate.
For and against
- Ink capacity that embarrasses pens five times its size
- Genuinely pocketable, posts to a usable length
- The cheapest way to try either brand — often under $10
- More colourways than any other model in the catalogue
- Eyedropper filling means ink on the fingers and burping if you overfill
- Tiny unposted
- Nib QC lottery at its most pronounced at this price
The brand's calling card: absurd capacity, pocket size, and cheap enough that a bad nib isn't a disaster.
What owners say
The Wancai is a unique design, that I have not seen anywhere else. I have my Wancai for about 5 years, dropped it a couple of times and it is still in a great condition. r/fountainpens · 11 pts · thread
both are solid but i'd go kakuno if you actually plan to use it a lot, it's more comfortable and reliable overall. wancai mini looks cooler and is super portable, but it’s more of a pocket novelty than a daily writer imo. r/fountainpens · 9 pts · thread
Hmm. This one is a tough one. I have 2 Majohn Wancai Minis, and neither of them having leaking issues, but they do have burping issues with excessive heat or altitude pressure changes (something that happens with any eyedropper pen) Did you have the pen in your pocket for a while? Or did you JUST ink it up? r/fountainpens · 7 pts · thread
I'm drawn mostly to demonstrators/ less opaque pens but this one is really pretty and I love that ink color. I recently purchased a Moonman Wancai that I enjoy. I could see this one eventually joining my newbies collection. r/fountainpens · 6 pts · thread
Your raden is beautiful! I love Wancai minis so much. Talk about a pen that brings joy. r/fountainpens · 3 pts · thread
Go back for it later if you decide you like fountain pens and still want it. Kakuno is reliable and not as annoying, since it takes cartridges and converters and has a snap cap. The Wancai mini has to be filled with an eyedropper and unscrewed to open and then screwed to post. r/fountainpens · 3 pts · thread
