The grey and black Spyderco BaliYo pen is stronger, smoother, faster and more fun than ever before. Its custom-formulated polymer components are also more durable than previous generations and are available in several vibrant color combinations. Improved spring-steel clips on both handles allow the BaliYo to be clipped securely in a pocket, but are also easily removable. It provides safe unlimited creative motion anytime, anywhere, even while sitting. 100% USA-made using high-performance materials and manufacturing. The BaliYo is 4.25 inches tall and weighs in at 0.85 oz. It uses a Fisher® Space Pen® cartridge that writes underwater, in freezing cold, boiling heat, at any angle, and even upside down.
