Here is Highlights' clip on my loose pony though if you want me to do a picture of the one in the box with my MIB one I can do. Let me know if it's okay, her hair is kind of bright so if need be I can take it off and photograph it.
I haven't found Ringlets' yet. I have a bad feeling there's a chance it is with the pony in storage, but I will keep looking in case it's in a different storage bag.
I did find two of the other identical bow clips in different colours (yellow and blue I think) which clearly are from some other line but look just like GH pony clips (unless there is a variation I don't know about). Are you going to mention those on your site as they often turn up in pony lots?
