You can search for Japanese figure-specific repair glue—something specially made for fixing anime figures or character models. Ideally, choose one that's non-toxic, odorless, strong, and comes with a long dropper. Hope your Dan Heng gets back in great shape soon!

My Dan Heng's earring broke off too! It's really fragile! But I fixed it with model glue, and now you can't even see any trace of the damage. I highly recommend using glue!
