Kilometrico

Kilometrico is a common model of ballpoint pen made by Papermate. It is available in red, blue, and black, in different point sizes. Kilometrico pens are inexpensive and write smoothly, but are also prone to leaking in some circumstances. Kilometrico pens are very reliable and work well in most circumstances. They are suited to tasks requiring a fine line like writing in comparison to colouring a large area.

The pens are so named because they are advertised to be able to write for one kilometre. In most cases they write for more than one kilometer.

It also has a famous advertising song associated with it.
