The Kyroh is a bolt-action pen that twists and locks into place and accepts replaceable Fisher Space Pen cartridges. The pen is fashioned with a textured grip, glass breaker, sturdy pocket clip, and replaceable Fisher Space Pen ink cartridge. The Kyroh is sure to be a solid addition to your everyday carry and is available in two sizes - a standard and a mini. It is the first of its kind to use the pocket clip as the bolt-action mechanism and we imagine it won't be the last.
