This little group all share a common problem - they lost the tips of their horns at some point.  If you see the photo, I actually removed the remaining horn from one of these and she makes a very sweet pony (but the lion tail...).  If you have a steady hand then a small hole and a replacement horn in clear resin (supplied) will take these from slight seconds to super-special little ladies.

Supplied in their custom foam lined boxes with replacement horn and collectible sticker.  One supplied.
