The gel rollerball reduced to the essentials - the Pilot Super Gel is its own refill. A tube full of ink with a ball on the end and a cap. As disposable pens go, it has the virtue of minimal components and materials, yet still offers high-quality high-performance writing. This pen has largely replaced the Pilot G1 for the more unusual colours. This pen is also known as the Pilot Neo-Gel in other markets. Features include gel ink, a direct ink system, a tungsten carbide ball, and a visible ink level. It has a fine 0.7mm tip.
