Wingsung 699 leaking
(sh.itjust.works)
I bought a Wingsung 699 recently from AliExpress because I wanted to try out a vacuum filler. Ink leaks from around the nib whenever I cap it, leading to ink getting on the grip. When I write, blobs of ink sometimes burp out onto the page. Is this typical for this brand? I have another no name Wingsung (I think it's actually a knockoff of the Hongdian dark forest) that has no issues.
I'm storing it with the blind cap fully closed.
That's interesting that the hand warmth can cause burping when the blind cap is closed, I had thought that closing the cap would fully seal the ink reservoir from the nib.
It does, but there's still some ink in the little section between the feed & stopper, plus ink in the feed itself.
Hmm right - you would think that the shut off valve should keep any expanding air out of the nib. between that and the leaking, maybe you just have a defective pen with some issue in the sealing of the shut-off valve?
