Perhaps one of the warmste color combinations of all is this M600 Tortoiseshell Red ballpoint pen! The warm coral and orange-red color blend marvellous with the gold trims! The barrel is made of high-quality resin that is polished to a high sheen. The cap is made of cellulose acetate that was very carefully manufactured and turned into a sleeve. All rings and the typical Pelikan clip are plated with 24 carat gold. Every single writing instrument is mounted by hand and carefully checked to fulfil the strictest quality criteria.
