I call this kind of box a “Schrodinger’s Box” as a reference to the fact that it’s made as one large box, and until you slice off the lid, there’s just no telling WHAT might be inside… Maybe even Schrodinger’s Cat

Ususally there’s just sawdust, but you never know….
The dark wood is walnut, the top is quilted maple with a walnut stripe.
Lovely work! Do you sell these pieces by any chance?
