Most Delta multi-pens and pencils use standard mini ballpoint refills and .7mm or .9mm pencil lead. We recommend Monteverde liquid ink mini ballpoint refills available in eleven colors. If you like standard ballpoint ink in your multi-pen, Fisher offers a mini ballpoint refill that can be snapped to the exact size you need. You can replace one of the ballpoint refills with a PDA stylus tip. Take a look at all your options shown below.
We also carry .7mm erasers for Delta Dolcevita and .9mm lead for the mechanical pencil.
