Pineider's Avatar Collection marks a step up in pen manufacturing that involves a new material (the revolutionary UltraResin), precision assembly (a new process called GlueLess), and the special protection of the cap lock. Joining incredible beauty and a very high resistance to any kind of impact, each Avatar UR is crafted with a mother of pearl compound resin in a special formula, called UltraResin. Developed in Florence specifically for Pineider, this compound is very stiff and its exceptional features makes it nearly unbreakable. Not only strong, UltraResin is also quite luxurious with an extremely glossy surface, mother of pearl sheen and marbleized colors. 
Rollerball pen uses standard Schmidt/Waterman style rollerball refills.
