Pretty nice looking keepsake in itself, even without something inside. Very nice work.
Regarding the tapered dovetail on the lid, first - glad I could provide an idea well received & useful. When I suggested it, I was thinking that it would limit removal to one direction, maybe keep from falling off when picked up. Based on your comment however, "It made the building much easier.", I'm assuming that you first make the top & bottom with dovetail, fit together tight, then turn it round. Huh, pretty smart move on your part. 👍👍
