Hi All, I am thinking about buying a new ebonite urushi fountain pen. Most resin and some ebonite pen caps have a cap ring, my understanding is the cap ring is to prevent cracking and chipping. Is my understanding for the need of a cap ring correct? If the pen does not have a cap ring do I need to be more careful capping and more gentle with the pen? Does anyone have experience or photos of ebonite pen caps that cracked or chipped? (I prefer not having a cap ring)
