This is a refillable Polymer Clay twist pen with a crab pattern and a blue and red background. The blue titanium and chrome accents highlight the crabs, and the true texture feel in your hand makes this pen a joy to use. Other than the fact that this pen looks cool, it also has a special grip. This grip allows the pen to conform perfectly to your fingers. This means that your hand will not get tired as quickly if you do a lot of writing. It is ergonomically designed to hold in your hand for a long time. It has a medium tip and only weighs 1.7 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!
