Secret Santa stopped by!

With an interestingly sized box, that has an interesting rattle when gently shaken. When can I open it? Has he visited anyone else yet? (he will be a little tardy getting to my Santee,though, as I just packed it up today for posting on Monday) Putting up the Christmas lights after supper, deck the halls, fa la la la la, God rest ye, merry gentlemen! almost to 75...oh and Happy Hanukkah too, latkes are so yummy!
