The Slider XB pack comes with eight colored ballpoint pens: black, blue, light blue, green, orange, pink, purple, and red. Each one is equipped with Schneider’s proprietary Viscoglide ink technology. The extra-bold points measure 1.4 millimeters, and the barrels are clear with rubber grips. The Slider Edge XB pack comes with the same ink colors as the Slider XB pack, and both pens feature the same Viscoglide technology. The difference here is the smaller triangular barrel, which is fully rubberized to provide better grip for smaller hands. Both the Slider XB and Slider Edge XB pens are filled with quick-drying ink and feature stainless steel tips.
