Caran D'Ache Metrub Fountain Pen
The Metrub series by Caran d'Ache is an exciting mix of rhodium and rubber. The barrel is clad with a hexagonal jacket of natural, refined rubber that is soft and resilient to the touch, with rhodium-plated clip and trim. The fountain pen has a threaded cap that screws on the back of the pen while you are writing. The Metrub fountain pen has an 18K gold and rhodium nib and uses cartridges or converter.
