X stylus is a convertible touch pen for the NDS game console. Like many other third party touch pens, before the transformation, the X stylus can be stored in the NDS pen slot, it looks and works just like the original touch pen. However, a simple flip to the X stylus will extend the length of the pen and expand its gripping area at the same time (the two requirements for good handling of any pen like object), making the X stylus the most user friendly touch pen on the market.
