Well Its not so much a box, it only has a shallow internal space, I sell them as Tooth Fairy Boxes (somewhere for parents to keep their child's first lost tooth.)
Anyway, its Blackwood, turned from one of those Pyramidal blackwood bells you can buy,
It stands 190mm (7.6") by 80mm (3.2"),
C&C as you will, and for those not registered, thanks for peeking.
