The Parker Sonnet Ciselé (Parker Sonnet Ciselé) is made of 925 sterling silver and features the world-famous interlocking squares pattern (Crosshatch Pattern) with pure gold-plated trims and edges. This engraving is a classic heritage of Parker, inspired by the company in the early nineties from its successful historic pen "Parker 75" to present the luxurious "Sonnet" collection that combines high craftsmanship and an elegant fluid writing experience.
