Excuse me, do you want to ask, "What should I do if one ear of the bear pendant falls off?" The following measures are recommended:

1. You can try to repair the ear of one of the bear pendants. If the pendant is missing or partially damaged, you can try to repair or modify it. You can remove the damaged part, or find a similar material as a substitute to keep the integrity of the pendant.

2. If the pendant is very important or difficult to repair, you can seek professional repair services. Some jewelry stores or art restoration studios may be able to provide professional restoration services to restore the pendant to its original appearance.
