This pen uses an green and pink Acrylic body, giving it the name watermelon seemed like a decent fit for these color schemes. The gold plating also givess it a more elagant pop to the stuning factor. This pen uses a parker style ink cartridge, and a cap that screws and unscrews on both ends. Just like all the Gnetleman pens we sell, it glides when in use and has a medium width body for comfort during prolonged usage.
