Tsa Tsa amulets.

tibetan Tsa Tsa.

Tsa-Tsa are earthen casts (often mixed with relics)
which are worn as protection, most often in reliquaries (Tibetan: Ga'au)
and sometime have impressive dimensions.
Tibetans also often keep in their Ga'au all kinds of small ancient objects
and strange stones,
and considered "loaded".
