DESCRIPTION: Simple, black, with six shiny lines revealing the brass beneath. The Brassing Rollerball Pen stands out for its exquisite appearance, but its functional design is also remarkable. The perfect weight balance provides a stable grip and a smooth writing experience. It's a real eye-catcher and a great gift choice. SPECIFICATIONS: Material: Brass. Specifications: 9.7 x 11 x 130 mm. Refills: Standard rollerball pen refill, SCHMIDT Safety Ceramic Roller 5888 F included. USE AND CARE: The ink will gradually wear away during daily use, revealing the brass beneath, which we call the "brassing effect." You can create a custom brassing effect by removing the surface ink with sandpaper, which is included in the product packaging.
