The soft ERGO grip with massage points are comfortable to hold and can be used by right-handers, left-handers and dysgraphics. The Tornado features a cap that can be posted while writing as well as a handy clip to add to affix neatly to your notebook. With blue eraseable ink the Tornado is a great addition to your pencil case whether you’re at secondary school, college, university or elsewhere. The rollerball is often thought of as a fountain pen substitute but we think it has it’s own place in every pencil case due to it’s water based ink qualities, super comfy grip and trusty 0.3mm line width.
