It'll probably fit a large pony or a smaller horse the best but as long as your horse doesn't have a ginormous head, or a really tiny one, there shouldn't be a size issue.
It's mostly pink but in some areas it has a really nice light purple sorta color (the rope was one of my tie dying experiments, haha).
It'll be $14.00 (that includes $4.95 shipping, priority mail)
The whole halter:
The nose area:
You can kinda see in this one how there's purple in some areas:
And here's Lacey wearing the one I made her from the same rope (she got the almost completely pink end, haha)
