Marlen's two models of desk sets.
Crystal, with a transparent base which designs the red and white Marlen logo (diameter 14 cm.)
Wood, with lacquered wood base
Each set includes a fountain pen - cartridge filled - and 14 kt gold M nib, and a rollerball, available in plain black resin or in striped brown celluloid with blue accents with black cap and ends.
The pointed bottom end, typical of desk sets, is unscrewable and can be exchanged with a normal end part (included); the pen may also be closed by a cap (included), then used and pocketed like any other pen.
