What is a gel ink pen?
Gel ink pens use ballpoint writing mechanisms with an ink in which pigment is suspended in a water-based gel. The gel ink is in a solid state inside the refill but turns liquid from the friction generated heat of the rolling ball. Once the ink cools down on the paper, it becomes solid again. Gel ink provides the user with smooth, effortless writing with vivid colours and no blobbing, and because the ink is thick and opaque, it shows up more clearly on dark surfaces. Gel ink is acid free and archival safe.
