Ballpoint pen

A ballpoint pen is a autograph apparatus with an centralized ink backlog and a apple for a point. The centralized alcove is abounding with a adhesive ink that is dispensed at its tip during use by the rolling activity of a baby sphere. The sphere, usually from 0.5 mm to 1.2 mm in diameter, may be fabricated of brass, steel, tungsten carbide,1 or any durable, adamantine (nondeformable) material.
