The Schneider Slider Xite ballpoint glides smoothly over the paper and can be used anywhere; from lecture hall to home to office. The pen features a push button with retractable tip and has a metal clip. The barrel is made of 90% biobased plastic and the pen is filled with black ink. This ink is smudge-free and dries quickly, allowing you to mark written texts almost immediately. The refill can be replaced by Schneider Slider 755 XB refill and Schneider Express 775 M refill.
