Won't hold up

I'm actually very disappointed with these keychains. The only thing keeping the ring on them is a tiny plastic piece that comes undone very easily and could cause someone to lose either the custom piece or one's keys. My order arrived with 2 of the plastic pieces popped off. I was able to re-attach them, but there is no "lock" to the mechanism. It's just a plastic protrusion that slides into a hole, and it can pop back out very easily. While these are great in every other way, I can't give them away and I certainly can't sell them, knowing that someone could lose a key using them. I will not be ordering again.
