Pen PIerre Cardin - The pen is a writing tool. It has an inner chamber filled with viscous ink, which is distributed during use due to the rotation of a small metal sphere. The ink dries almost immediately after contact with the paper. The ink used in the pen wets the ball under its own weight. So when you put the pen up with the ball, it stops writing. The pen may be needed even in the most unexpected moment, so it's good to have the popular writing instrument at hand at all times. Size: h = 13 cm.
