I have Mini Kit and Mini Nellie. Mini Kit is adorable; Mini Nellie is cute too, but I honestly don't think her face is nearly as cute. Her clothes are much neater, though! Check Kirsten's Adventures if you'd like pictures of them (the most recent or second-most recent, depending on when you read, are the best bets for Mini Nellie).

The only other mini I've seen IRL was Mini Kaya, and she was just beautiful.

(I ordered Mini Nellie from Amazon and she was supposed to come with trading cards and maybe another book but she didn't. No real loss; it's not like I need that stuff cluttering my place. But I thought I'd let you know. I guess your boxes would be clearly labelled though!)
