So there's no metal at all in it (screw, nails...) like in the good old time.
Sometimes I work a little bit on wood too and I have the same feeling. When I look at a modern objects I only see a industrialized, mechanical, soulless, standardized item.
But when I look at a creation, like your box, I can see it's unique, you can picture the movements of the craftman, the tools shaping the wood, the uniqueness of the shape, the search for colors balance, dimensions harmony, perfect adjustments...
