The Zebra bLen retractable gel pen features an internal system that eliminates writing vibration. A lower center of gravity was established by placing a brass weight at the tip of the pen. The weight allows for a smooth and gentle touch to the paper, allowing you to experience a stress-free writing experience. It also features a noise-free design that eliminates gaps in each part inside the pen. Created in collaboration with nendo, a Japanese studio, the bLen Gel is not only pretty to look at, but can eliminate stress with its innovative design.
