So I recently purchased a TWSBI Vac Mini in Smoke from my local fountain pen store. I must say the filling mechanism is super cool and it writes really well, however, I am having an issue with it and I am seeking FPN community input. Today when I was writing, I noticed some ink drops on my thumb and the side of my middle finger where the grip section/cap threads would normally rest on my hand. My immediate thought was that there was a crack in the pen and that it was leaking onto my fingers. However, when I ran that section of the pen across some paper, there was no ink left behind nor was there any additional ink drip after more writing. I inspected the grip and cap threads with a flashlight and a laser pointer to see if there were any cracks and failed to see anything (in a way this was perhaps unsurprising as I never dropped the pen before).
This left me thinking, could it just be ink trickle from being bounced around in my knapsack, or is there actually a crack in the pen I should look to get repaired? Has anyone else experienced something similar before?
Thanks for any input!
