Wait for beenburned or hyacyth. The box says Jack Russell Terrier on it.
Confirming the Scottie is fake.
The keychain in question is fake.
I don't recommend rbrannagan. The seller appears to mix authentic and fake Coach keychains and in fact, at least one of the possibly-authentic charms has a fake box used as a prop.
I am not sure of the authenticity of the multi-stars keychain but I don't believe it's made in the colors shown. Please wait for other opinions on that one.
Thank you so much. Greatly appreciate all of y'alls help!
