it's just a plain ol' black XL. i also lose like a million styluses every year. right now it's pink. the tip is broken off which makes it hard to type in animal crossing sometimes but it works
I play ACNL on my HHD ds with the isabelle bottom plate and the HHD plate on the top! I've also got a red n3dsxl that I play my new town on since it's a digital copy. c:
Mine is the limited edition Pikachu 3DS XL. There were only five at my local store. Ironically, I play more Animal Crossing than Pokemon on it nowadays.
