The Stabilo Easyoriginal is an ergonomic rollerball and cartridge designed for young writers and students aged 6 and up. It is the first rollerball with an ergonomic design suitable for both left-handed and right-handed users. The grip zone is made of non-slip material, allowing for a relaxed hold and helping to prevent premature muscle fatigue and pain while writing. The pen offers an easy writing experience that ensures clean writing without smudging or scratching. Each new cartridge comes with a new writing tip for guaranteed easy refilling. It can be refilled with royal blue, washable school ink, black, or red ink. The cartridges are available in two line widths: 0.3 mm (fine) in blue for finer writing and 0.5 mm (medium) in blue, black, or red. The pen features a field for name inscription, and the cap can be attached to the end of the pen.
