This unique gel ink blend is slippery-smooth and designed to give bold lines every time, saving your customers from skips and scratches that can ruin an otherwise excellent writing experience. Our exclusive Gelebration gel ink is used in all National Pen brand gel pens. While some of our home brand gel pens feature Gelebration in the title, you can be sure that if it’s a National Pen gel pen, it has our exclusive Gelebration ink inside.
