أجزاء القبضة وأطراف قلم الحبر البلاستيكية الهندسية

The Schmidt inkball tip fits perfectly into my full-sized pen body, and the engineered plastic grip feels surprisingly sturdy. I've been using it for a week now, and the ink flow is consistently smooth with no skips.

I was skeptical about mixing fountain pen components with a ballpoint tip, but the Schmidt inkball tip writes smoothly right out of the box. The grip section fits perfectly on my full-sized aluminum pen without any wobble.
