I also have the Itoya needle point gel refills, but I haven't put or used any in any of my Parker pens yet. I also ordered and bought mine on eBay from Temecula too after reading your post two weeks ago. The seller took forever trying to ship the refills to me. I finally got them delivered to me just late last week. I purchased both the 1.0 mm in blue and the 0.7 mm in black. The seller didn't have any 0.7 mm in blue and I'm really disappointed about that. What do you mean when you say that they are not water resistant? Is the ink that's inside the Itoya needle point refills like fountain pen ink? Does it fade and run on the paper if it gets wet? Why isn't it water resistant? Please explain.
I love the Itoya needle point gel refills in all my Parker and compatible ballpoints. Clear refill so you know when it's done. Water resistance is not a feature, regretably.
No affiliation, but I buy by the dozen on fleabay from the guy in Temecula CA.
