The drawer in the box fits precisely so that it does not slide out on its own after the box is closed, keeping the contents inside safe. The drawer cannot be inserted into the box all at once. It is necessary to slide the drawer into the box piece by piece. It's very difficult at first, but it gets easier over time. The drawer is opened using the handle on the front or the oval finger hole on the back of the box.
The author marked this model as their own original creation.
