Mauna Recycled PET Gel Rollerball (black refill)

The rollerball is made from recycled PET plastic, which helps to reduce the amount of new plastic. The ink in a gel pen consists of a combination of water-based and oil-based components, allowing for a smooth and consistent writing flow comparable to that of a fountain pen. This type of ink is also known for not fading, making it popular with artists and writers alike. Gel pens have a fine tip, which allows for precise and controlled writing.
