The Cleo Aura is a compact fountain pen made of a precious resin. The Mother of Pearl finish literally sparkles when it catches the light, giving it an amazing depth. The Cleo Aura features a very smooth 14-Karat bi-color gold nib available in extra-fine, fine, broad and medium sizes. It has rhodium-plated fittings and pen clip with a screw-on cap that posts securely. The pen utilizes a cartridge/converter filling system and can be used with any standard converter. It comes with a blue international standard ink cartridge.
