The curator of the museum tells us that such oval amulet boxes are known as kerima, which means kidney, due to their shape.
Shaped like a duck, this jug was possibly used to serve chang (a cereal-based alcohol). There is a lotus bud finial on the lid and medallions with Kirtimukha and auspicious symbols around the body.
The shape of the amulet box on this necklace is unusual.
The historical buddha is seated on a lotus, calling Earth to witness with his right hand, the other holding an alms bowl. In front of him, there are two arhats.
A torgam is a sort of cupboard used to keep offerings to wrathful deities made of butter and flour called tormas. The doors above depict Mahakala, some cups made of human skulls resting on three skulls, containing tormas and other offerings (see below).
The above skull cups both contain offerings related to the five senses (eyes, ears, heart, nose, tongue).
This is most likely a piece from a ritual bone apron used for Cham dance.
