Finishing a wooden storage box

I'm not really a crystals person, but they seem to insist on finding their way to me, so I might as well make some nice storage for them. I found an unfinished wooden storage box, that had internal dividers. I was pleased when it turned out that they weren't really glued in, and with some persuasion I could remove them. They were the height of the body of the box, but the tumbled stones are small, so first thing I did was trim the dividers down to half height. The interlocking mechanism meant I had to remove a quarter from the top, and the bottom of each piece. The mystery wood is very soft, so all I had to do was score the wood a few times with a utility knife, and then snap the excess pieces off.
