The Invincias have a large contoured profile that is well-balanced for writing comfort. There are 3 finishes that contrast and compliment each other perfectly: rose gold/gray carbon fiber mirror chrome/gray carbon fiber and the spectacular mirror chrome/tartania carbon fiber. The tartania carbon fiber is a technological breakthrough that combines many colors on many levels.
