Slim Pen is a new concept for a pen designed to fit today's needs for efficiency and portability. The crux of the product is that part of the pen (a docking tab) is permanently fixed to the inside of a notebook or agenda. This feature allows the pen to be removed and replaced in one easy movement. The user benefits from his / her pen always being available for use and protected from damage or loss during storage. The docking tab is ready for placement thanks to an adhesive pad and is placed inside the cover of the notebook / agenda only one time. Slim Pen is designed to be thin but ergonomic and comfortable for writing.
