Caran d’Ache takes writing to the next level of high quality and innovation with its new RNX.316 fountain pen. The name is code for the fusion of round and hexagonal - Caran d’Ache’s two iconic forms. The combination creates a fascinating design and a perfect grip for writing precision. The new Swiss-made series draws its great strength from its material: 316L stainless steel. The RNX.316 collection is available in two versions: Steel and PVD Black. The Steel model features a guilloche spiral pattern achieved by a special engraving process. Both styles offer a simplicity and finesse that are a pleasure to the eye and to the touch. The RNX.316 Steel fountain pens are distinguished by a PVD coated, stainless steel nib that gives you writing comfort and fluidity. An innovative system allows for easy refill changes on the fountain pen and rollerball: unscrew the pen end and a counter-screw mechanism advances the writing block. The ball pen and 0.7mm pencil have high-precision push-button mechanisms. Rediscover the pleasure of handwriting with the new shape and advanced technology of RNX.316! Cartridge/converter fill.
