The Stabilo Easy original is an ergonomic rollerball pen designed for beginner writers and students aged 6 and up. It is the first rollerball pen with an ergonomic design suitable for both left-handed and right-handed users. The grip area is made of non-slip material, allowing for a relaxed hold and protecting against premature muscle fatigue and pain while writing. This pen enables easy and clean writing, as it does not smudge or scratch. Each new cartridge comes with a new writing tip, ensuring easy refilling. It is refillable with royal blue, erasable 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. There is space for a name engraving, and the cap can be attached to the end of the pen.
