Spyderco BaliYo Twin Handled High Performance Heavy Duty Pen - Grey - YCN101;

The Baily is a toy that promotes ambidextrous hand/eye coordination and helps develop fine motor skills. Baily offers an unique concept in pens, made using high-performance materials and manufacturing. It provides safe unlimited creative motion anytime, anywhere, even while sitting. Constructed from three pieces of close-tolerance polymer, the center body is a pressurized ball point pen pivoting between to two parallel arms. The positioning dynamics of the pivots allow you to swing and rotate the pen, changing its speed and force of gravity while flipping and twirling. Refined symmetry with even weight ratio (end-to-end and side-to-side) balances the pen through motion and force. With practice you can learn sophisticated moves, two-handed tricks, quick-flips, spins, aerials and how to manipulate combinations of these. Basic tricks are easy to learn, and an illustrated foldout instruction guide is included. While the Baily is fun for all ages, it does have a few small parts and is not for children 5 and under.
