Whatshisgame points out that these may be a part of the My Little Pony Miniature Collection found on this press release near the bottom. The seller (Located in China) also has a whole pile of toys from other franchises that are unreleased. He also has a few of the upcoming blindbag toys for auction.
If they are fake, they are pretty amazing customs! I'd buy all of them.
