These stylus pens do not match the original stylus from Storio 3S. There are more pins that are expected from Nintendo ago. Small, round and shaped like a pen. But you do their job on Storio and are therefore a good alternative or replacement. They even fit in the penholder from Storio without you fly out there and get lost (which has even surprised me a little, after all, the original pen is designed flat and wide, like a flat-pressed oval and even the pen tip is slightly larger than that of this Pens).
