The dents in the plastic pop back out when removed from the box so don't worry too much about that
All my G3's who had that lost them in a matter of days. I seem to recall the ponies with names on thier legs were a bit harder to track down. I think sweetiebelle was the most difficult if memory serves, but I'm not sure how that effected Rainbow dashes Value.
I can't give you an accurate price check but I wanted to at least say not to worry about the plastic denting, thats pretty standard G3 and it perks up
