Excuse my ignorance. . Altho' I have heard of "gel" ink refills, I don't know how they differ from "ordinary" inks.
I got this blurb from the ExoticBlanks website using the link that Jim gave above:
" This new Monteverde Capless Ceramic Gel refill allows you to convert your ballpoint pen into a Capless Rollerball.
The Monteverde refill offers:
• For the first time ever this refill offers a
combination of a ceramic ball with gel ink
• Smooth, comfortable writing
• Finest developed inks
• Stainless steel tip with ceramic ball "
I would appreciate a brief account of the advantages of "gel ink" and "ceramic ball", please, if anyone would care to oblige me ! . Thanks.
