Star Sprint

I recently saw a pony pin at a friend’s place—it’s got Twilight Sparkle on it! She doesn’t know where it originally came from, so I thought I’d ask here if anyone knows its origin. Applejack is my favorite, so I’m really curious if there’s a version of this pin with her. I’d love to add it to my collection! Also, if anyone has this pin series, could you share what the other characters look like? I’d be super grateful. Thanks so much in advance for any information!
