I wanted to know how big the stylus is. (Length and measuring of the respective devices) It is also sufficient for me to get only a comparison, which pencil is longer, shorter, wider or wider.
I've just measured on my 3DS XL, there's the stylus 9.7 cm long (+/- 0.1 😉)
What I also mean to know is that they had a different size for the older DS / DS XL, as they do not have the slot in the 3DS slot (they were probably shorter and slightly different shaped at the top / the old ones were square and not round) How long these are I can tell you but now on the fast no.
