N.B. Each kit is supplied as the components only and does not include the material / blank. Our Rollerball Pen Kit is supplied with a gold plated writing tip and a high quality German made ink cartridge. The Rollerball pen writes a dark, medium point line and is a total pleasure to use. The 24kt Rollerball Kit is similar to the 10kt but has a black stripe down the clip instead of the famous Artisan logo. A quality ink cartridge is supplied with all kits. We recommend the use of the cap adjuster tool (210083) to aid assembly of these pen kits. Requires 10mm drill. For refills order 340240. When using a mandrel to make these pens the 310387 Bushing Set will also be required.
