Description The Visconti Opera Master Limited Edition Savanna features a stunning semi-translucent yellow, brown, cream and white swirling resin, accented by palladium trim. The Opera Master Savanna is limited to 888 fountain pens, and each one is each individually numbered. It uses an oversized 18kt white gold nib, closes via the hook safe lock, and fills via the double reservoir power filler.From Visconti:transports the pen collector to the fascinating landscapes of the African savanna, where lions, zebras, and elephants roam in the wild. The savanna landscape changes with the passing of the seasons, from the dry heat of the plateaus to the wet rain of the tropics. The predominantly yellow shades of the dry season shift into thousands of brown hues typical of the rainy season. These two seasons come together in harmony and are united not only in the heart of Africa, but as well in the barrel and the cap of the new Opera Master Savanna. This is an exceptional fountain pen featuring the many patented innovations favored and sought out by Visconti collectors:Double Reservoir Power Filler: A vacuum filling system that is easy to use and has considerable benefits. Patented in 1998, this is arguably the most advanced filling system ever developed in fountain pen history. The user is able to fill the pen with the equivalent of 10 cartridges of ink, and thanks to the two reservoirs, prevents ink from leaking during air travel.Hook Safe Lock: This revolutionary closing system is very satisfying to operate and was created to lock the pen body into the cap to prevent the possibility of the pen accidentally unscrewing and leaking inside a pocket or bag.Semi- transparent demonstrator: The Savanna features a semi-transparent resin cap and body with beautiful swirls of yellow, brown, cream, and white inspired by majestic savanna landscape. The beloved Ponte Vecchio bridge clip features a light yellow enamel to accent the Visconti name.18k gold in-house nib, hand crafted and manufactured in Florence, Italy.In 1998, Visconti applied for the Italian patent for its Double Reservoir Power Filler, a unique filling system that allows a massive ink capacity and safe usage during air flights. Similar in operation to vacuum-filling pens (such as the larger Visconti Homo Sapiens), the Opera Master fills with a 3.4ml ink capacity in the sealed ink reservoir. Unique to this design, there is a second reservoir in between the vacuum seal and the pen’s feed that holds about 0.6ml, the size of a typical standard international short cartridge. Effectively, what you end up with here is the ink equivalent of a standard international cartridge that you can use to write (without having to unscrew the filler knob like you do with most other vacuum-fillers), with the contents of an entire pack of cartridges (or the entire Visconti Traveling Inkwell!) in the back of your pen.We also offer customization of your new Visconti Opera Master Savanna with the magnetized MyPen System. We offer natural stones, your initials, or zodiac coins that you can swap into the finial in place of the Visconti logo coin.As of April 2023, all 14k and 18k gold Visconti nibs have been inspected and tuned by a nib worker and despite our best efforts to fully clean each pen may exhibit some minor traces of ink in the nib and feed, but have in no way been filled or previously owned or used.
