This set includes the pen, gift box, four ink cartridges, a piston converter, a certificate, and a 3-year warranty. The fountain pen ink refills are standard-sized cartridges that are compatible with a wide range of fountain pen ink refills on the market. This is a premium, handmade fountain pen made in Germany. It features a gold-plated stainless steel medium nib (0.5mm), chrome-plated brass hardware, and an iridescent AAA-grade mother-of-pearl inlay. The twist caps feature a matte diamond-like coating (DLC PVD) with an additional layer of ultra-high strength carbon to protect the metal surface. Xezo uses saltwater mother-of-pearl, which has a hardness of 4.5 on the Mohs scale (the same hardness as iron). As a result, color and texture may vary. This is not a defect, but a natural characteristic that makes your pen unique. Diameter: 13 mm. Length: 148 mm. Weight: 48 g. All Xezo writing instruments are guaranteed against all manufacturing defects and parts for a period of three years from the date of sale. This handmade fountain pen features a chrome-plated stainless steel nib, chrome-plated brass fittings, and a mother-of-pearl panel. The cap is matte black with a DLC PVD coating for durability. DLC (Diamond-Like Carbon) is a special PVD coating that bonds carbon atoms (the components of diamonds) to the pen's surface. This advanced process simulates the effect of a diamond layer on your pen, providing all the protection you'd expect from a precious stone. We believe that using mother-of-pearl shells offers exceptional results that are well worth the effort and expense. We use mother-of-pearl with a hardness of 4.5 on the Mohs scale (the same hardness as steel). Mother-of-pearl is a natural material, and each piece is unique. This can result in variations in color and texture, but it also adds to the uniqueness of each pen.
