This leather box is made from harness leather that has been hand-sewn with brass rivets added in the pattern of a die. It was then lined with thin wood, oak in this case. The general price of boxes of this size is about $50.
The Hex box was lined in cherry wood, and it is also possible to make a box out of only leather like the brown box with a celtic knot on the lid.
This Box is 4" on a side.
