Cup used by religious jews during ritual washing of hands before eating. Typically has a handle on each side as the ritual motions involve both hands. Can be made out of anything from plastic to Sterling silver.

"Netillas yodayim" translates into "washing of the hands", which comes from the prayer, translated into English, below.

Blessed art thou Eternal our God, ruler of the universe, who has commanded us concerning the washing of the hands.
