Divina by Visconti plays upon ancient themes of perfect proportions. The five-sided spiral crafted in bronze steel rods are buried in swirls of green resin. The fountain pen's filling system is through the top of the body and is referred to as 'Pull and Turn". You simply pull the knob out a bit and twist to fill the reservoir; that's it. The nib is 14k gold. The rollerball uses a standard-sized refill. The ballpoint is a precision twist-action. It is a one-piece, drop dead gorgeous, piece of jewelry.
