Retractable Ball Pens

Listing ID #1255350

We are offering retractable ball pens. A ballpoint pen (philippine english: ballpen, british english: biro) is a writing instrument, with an internal ink reservoir and a sphere for a point. The internal chamber is filled with a viscous ink that is dispensed at its tip during use by the rolling action of a small sphere. The sphere, usually from 0.5 mm to 1.2 mm in diameter, may be made of brass, steel, tungsten carbide, or any durable, hard (nondeformable) material.
