Here are all 12 boxes I finished them all this weekend (finished 10, 2 were already done). They all have a single lift-out tray. The box interiors are sleeved as well. All interior parts are friction fit and removeable. I did glue the suede in the lift-out boxes but the leather on the bottom is held in by the interior parts. All boxes are finished in clear Danish oil with the exception of the top left and top right in this picture which were part of a previous batch of 3 boxes of this same style. Those are finished in gloss and satin polyurethane. I will charge more for the gloss finish box since that is a MAJOR PITA to do.

I make the interior parts friction fit because when I make my music boxes, the musical movement needs to be able to be removed should it ever need service. I got into the habit of making all boxes with removeable interiors. Interior is comprised of 8 individual pieces. 

Boxes are Walnut, Maple, Ambrosia Maple and Mahogany. Walnut costs 3x as much as Cherry but not sure I will charge more for the Walnut boxes.

The lift out trays are made in pairs. See pics below for this technique. Not sure I invented this but it works very well for making consistent boxes.

Really torn what to charge for each box. I have around 6 hours of work and $25 worth of materials in each.

Also built myself a beveled miter sled for this project. I have no clue why I did not do this sooner. Wow what a total time-saver!
