Ritter-Pen's ecological ballpoint series demonstrates environmental awareness. For example the two models Bio-Pen and Bio-Star comprise of 80% regrowing, compostable materials, whereby the material cellulose acetate stems from European soft woods and complies with the DIN EN 13432:2000-12 norm. In the case of the Bio-Pen only the frosted mechanism case ans mechanism are maed of ABS plastic in order to guarantee the perfect functionality of the opening mechanism.
Due to the peculiarity of the material slight colour deviations on the barrel and clip are possible with both models. This also applies to the eco writing instrument Organic, wich is made of 90% regrowing, biologically degradable cellulose-based material. The pusher of the Organic has a frozen optics and is made of ABS plastic.
Last, but not least the ballpoint Bio-Mix attracts attention with its barrel made out of recycled paper. Whereas the pusher and bottom part are produced from regrowing, compostable materials, ABS plastic is also implemented for the mechanism case and mechanism. All models are fitted with a high-quality Jogger refilto ensure immaculate writing.
The series is rounded off with the Memo-Set II Bio, which compromises of a Bio-Pen and a 80-page notepad made of recycled paper, its cover can be customised with a 4c imprint.
