This is a custom hard rubber Shawn Newton pen with a vintage Waterman nib in it, configured as an eyedropper. Last year I dropped it and broke the section at the ink window, which Shawn mended for me. It wrote okay after that for awhile but not really. It had the common eyedropper problems of blorping but this wasn't when it was near empty but just say three quarters full. And then it started writing very poorly. As though ink could barely get through to the nib.
Upon refilling it would not start without dipping it in ink, or shaking it until drops flew. And it grew steadily worse, writing more dry and skipping all the time until I gave up struggling with it. This is a beautiful (and expensive) pen with a glorious flexible nib in it but something is clearly bigly wrong with it.
I am emphatically not a mechanically-minded person but I am hoping for something to try that may preclude me sending it out yet again.
