The BaliYo Heavy Duty Butterfly Pen by Spyderco is a toy that promotes ambidextrous hand/eye coordination and helps develop fine motor skills in a whole new way. Dubbed the butterfly knife pen by many, BaliYo is just that, only better and without sharp edges or blades. It still allows you to perform fancy tricks like the ones you can do with a butterfly knife, but goes one step further. BaliYo allows you to flip in ways that would be impossible with a blade swinging all willy-nilly around your hand, making it safe and fun for just about anyone.

Dependable Quality

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. BaliYo pens carry Fisher Space Pen Company's pressurized ink cartridges, known for writing superiority in any environment - ocean to orbit. Additionally, the BaliYo uses flexible wire clips that allow you a variety of clip positions.

Unique Skill Builder

The BaliYo provides safe, unlimited and creative motion anytime, anywhere. The BaliYo Butterfly Pen is the first skill toy of its kind - it turns an everyday writing instrument into a skill game that will provide endless entertainment wherever you are. You don’t need a large open space or need to be standing. All you need is a BaliYo and your fingers and wrist will do the rest (after a little practice, of course!)
