This is a twist-style refillable pen that pays tribute to the Irish people in your life. The Celtic Scrollwork is filled with dark green resin. The accents of antique brass display more scrollwork etched in the metal and topped with an emerald cabochon. The tip is medium and weighs 1.6 oz. All of our pens come with a free black ink refill. We offer a variety of ink colors, including blue, red, green, and purple. If you would prefer a different color ink, please send us a message, and we will be happy to change out the original ink for your color of choice. When it's time to replace the Parker-Style refill (see photo for details), turn the bottom counterclockwise. There is a spring inside, so be careful not to lose it. Thanks for stopping by our store!
