Still guessing?

This is the other side of Matt's birthday gift to me:



Yesterday I posted this side of the gift and asked for guesses as to what it might be, both on this blog and on facebook:



So far, nobody has a clue.
Judi guessed bicycle seat
Suzie guessed light switch cover
Randall guessed incense burner
and everyone else I've talked to can't even render a guess.

Therefore...I was asked for hints.
1. It's smaller than a bicycle seat.
2. It's about the size of the palm of your hand.
3. It's one piece.
4. It's hollow.

I feel a little better about not knowing what my one and only thoughtful gift was. I'll explain more of why it was thoughtful when I tell you what it is. Happy Guessing. :)
