The Uni-Ball Gel Impact Pen ink delivers rich, saturated color, and is the best-selling gel opaque writer in our stores. This pen works great on dark paper and behaves similar to a typical rollerball, yet holds this unique opaque gel formula for ink. The pen provides smooth writing with a contemporary barrel design featuring a rubber grip that provides comfort and control. Ink is acid-free.
