The pens in this series were produced in three different sizes. There are also variants that have different clip version. The first version is the classic arrow clip of [[Tabo Mentis]], the only maintained in the subsequent period. To this version was added a brooch shaped plain clip, used in older versions, and a curved, triangular terminated clip, with an arrow relief outline, used in a later time. | The pens in this series were produced in three different sizes.
