Is Danny messer's 项链 a medical tag 或者 something else? I know the one is his rind but what is the other one? Plese help!!! It is driving me crazy not knowing!!! :)

Thanks

they are his grandfathers 标签 i think

I beleive they are too, since in one episode when Danny has bad back pain, he goes to a accupunture, and then gets those, along with a few other items stolen. He calls Linsday and says "my grandfather's 标签 were stolen."

In fact, His Grandfather's name is on them
