The Ritter-Pen refills are available in a variety of grades, with various writing length and thickness. Individual parts of cartridges, such as housing, ball, ball bearings and paste are matched in a way that provides consistent ink outflow and, thus, a clean line, comfortable writing and durability.

When deciding on which product to place your advertisement, pay attention not only to the external appearance. Quality should rest in each detail – also inside the product, in a seemingly invisible but important place in the case of pens.

All Ritter-Pen refills meet ISO 12757-01 and 12757-02 standards.
