Chin may have eaten metal

[Angrychinchillas]

We bought a new hanging chew toy that said it was ok for chins and had decent reviews but clearly was not. We should have known better. Our girls snapped the wire and we can only find one chewed end that keeps the blocks in. We think they likely ate the other one. They are acting fine and energetic and we will contact a vet but wondering if anyone has experience with this. Picture of an unused toy end like the one they likely ate attached.
