Answer 1

Explanation:

The cap, barrel, and ink tube are made of plastic, while the ballpoint and tip are made of metals. The barrel of the pen is made of polystyrene, a cheap, mass produced plastic.

Answer 2

A ballpoint pen dispenses an oil-based ink by rolling a small hard sphere, usually 0.5–1.2 mm and made of brass, steel, or tungsten carbide. The ink dries almost immediately on contact with paper. The ballpoint pen is usually reliable and comes in both inexpensive and expensive types.
