The Canopic Jars are in a brown box measuring 4X3X3. 

This set of small canopic jars looks very authentic. They were used by the Ancient Egyptians during the mummification process to store and preserve internal organs for the afterlife. The canopic jars were placed inside a canopic chest and buried in tombs together with the sarcophagus of the dead. It was believed the dead person would need their organs for the afterlife.

The gods  Duamutef, the jackal-headed god representing the east, whose jar contained the stomach, the falcon-headed god representing the west, whose jar contained the intestines and  Hapi, the baboon-headed god representing the north, whose jar contained the lungs. Imseti, the human-headed god representing the south, whose jar contained the liver.

Because Tutankhamun died prematurely, there was no time for extended tomb preparations. And the 70-day burial tradition gave craftsmen little time to finish crucial tomb items, many of which required a year or more to make. Those objects include a carved stone sarcophagus that encased three nested coffins, four shrines, hundreds of servant statues, a gold mask, chariots, jewelry, beds, chairs and an alabaster chest that contained four miniature gold coffins for Tutankhamun’s internal organs removed during mummification.
