Inspired by carbon fiber, the Caran d’Ache RNX.316 Fiber roller pen features a marvel of entwined braiding, achieved with the precision and power of a laser. The writing instrument’s highly polished finish provides a dramatic contrast to its matte decoration. It is equipped with an innovative cartridge-changing mechanism, activated by a simple turn of the pen’s end, and an ingenious click-in system for cap closure. This pen, which uses a fine-point roller cartridge, guarantees unparalleled handwriting accuracy.
