I lost my favorite pen.

I bought a fountain pen yesterday.

I bought two fountain pens yesterday.

I bought a blue ballpoint pen.

I bought three stylographes yesterday.

The stylograph was widely used before the invention of the ballpoint pen.

The stylobate is the part of a Greek temple on which the columns rest.

Stylographic pens are very popular among writers and artists.

This stylographic pen is perfect for writing.
