Majohn P139 Expedition Pen Unbox

Unlike other P139 reviews, this channel is independent and unaffiliated with any commercial setup.

Disassembly:
   • Majohn P139 Piston Disassembly  

The first leak of this pen dated back to Nov, 2023. After some regular delays, it was launched yesterday.

The high price due to:

1. ebonite feed - but it does not come with Low Ink Refill function

2. all metal piston components - why? MB Hemingway with all metal piston mechanism?

so, both "upgrade specifications" do not actually deliver any "upgrade in function".

Pro:

quite a bit vintage pen look, homage to MB Hemingway, don't sleep old man don't sleep.

Con:

1. expensive, compared with other makers with similar specifications.

2. no Low Ink Refill function.

3. when posted, the cap will rest on piston knob and turn it with ease (pictures near the end). (newly added, found out after 24 hours of ownership)
