My kid used to collect them, now I just collect the funko pops, and a few of the mini's. Not mlp though. I have been debating on rather or not to list my Fluttershy chase vinyl on here... ;)
I collect horror, video games, and "some" Disney. I think I might try eBay out first, as I have a lot of mini's and pops to get rid of, I guess what doesn't sell though will be listed here. I have listed a few and so far only one has bids.
I don't know what she is considered as? She isn't a funko pop. She comes in a black box. Her variant is she is glitter the normal one is just yellow and pink. Rainbow dash also has a black bodied one. She is larger then a pop. They are anywhere from $30-$40 on eBay.
