For and against

  • Large eyedropper capacity
  • Clear acrylic shows the ink well
  • Eyedropper burping in warm hands
  • Pricier than the pocket eyedroppers without a mechanism to show for it

A solid demonstrator eyedropper; the pocket models do the same trick cheaper.

What owners say

Yeah, back-heavy pens are definitely kind of "egh". I think my two favorite Majohn eyedroppers that I own are a C4 and S5. Both of those do be burping though. Oh, and wancai minis. I hecking *love* those little bastards. r/fountainpens · 2 pts · thread
Majohn *also* makes an eyedropper with a shutoff called the C4. I have one, and it works great. Pretty chonk pen though... not quite Q3 chonk, but still. r/fountainpens · 2 pts · thread
I have one that I installed into a Majohn C4 and it's just lovely. I don't know if I'd consider it a "true" flex nib, but it has nice line variation. At the price? Totally worth getting a couple. r/fountainpens · 2 pts · thread
