#gwiitb Round 7 !

Here is the box for Round 7 of Guess What Is in the Boxes. It is 6" x 6" x 4.5# and weighs 11 oz. I don't have anybody handy right this moment to shake the box and describe its heft, so I will do my best to provide a disinterested description.

The weight is evenly distributed, but the object feels dense and does shake back and forth laterally, hitting the sides in a couple of places but otherwise well packed with something quiet.

Guesses will be accepted until Tuesday, March 31, at 4pm EDT. New players, please see earlier entries and the original post for guidance. Also, please tag your guesses #gwiitb. I am glad you are here, and happy guessing!
