XTS Solid Titanium Pen + Stylus

World’s First Titanium Pen that works with 30+ pens. We’ve spent the last 5 months designing and making numerous changes in order to make the most versatile pen possible. While making a TA4 titanium pen from clip-to-tip is really cool and unique by itself, we felt that was not enough and challenged ourselves to add a truly revolutionary feature. Our pen accepts more refills & brands than any other pen. Ever. We like to think of it as being a refill-ninja.
