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.

There are also different version for cap band, a band between two rings, a single thick ring, and three thin rings.

The models with shaped arrow clip were associated both with decorations with three thin ring on the cap or with a greek motif band between two thin rings. The body and cap were slightly tapered and ending in a conical shape both for cap bottom than the end of the body. The clip was inserted in the cap by joints, as it was done in a single piece. Although they were considered the oldest, their presence in more recent advertising casts doubt on the history of these style changes.
