Double Barrel Twist Pens
These ballpoint pens have an upper and lower portion typically with a center band separating them. The pen tip is exposed by twisting the two halves. Most double barrel pens will only twist in one direction, while others (like the Cigar pens) can be twisted in either direction. These pens come in a large variety of shapes and sizes. You are sure to find just the exact one to fit your personality.
