This is the lid part of a jar based on the canopic jars used by the ancient Egyptians for their mummification rituals. It is in the shape of Anubis, the god associated with mummification and the afterlife in ancient Egyptian religion.
This part measures 9.82cm tall, 9.33cm long and 6.95cm wide at 100% scale.
The base part of the jar that it fits into is available in my shop.
