I converted this pen to an eyedropper. I filled the tiny holes in the end of the
barrel with super glue. Took a couple of applications. Blow into the barrel to
determine if you have a good seal. Greased up the threads with silicone grease.
No o-ring. Filled with Noodler's Cactus Fruit.
There has been some migration of ink up the threads, but no leaks. Will keep you
I am obsessed with this pen! I bought a whole box of them (10)!!! The fine
writing line is perfect for fitting a lot of information in a small space.
Especially filling out forms. I used to be a business person and was very strict
about using black ink. Whatever. I then switched to blue ink feeling it was more
expressive. The blue/black ink gives a perfect balance of color.
