Inside are 4 little cedar blocks glued about 1 inch below the side. The two on the left help hold the brass handle (from Home Depot). I added a teenut in the center floor, near the back, after guessing where the box would best balance when open. There's also a piece of wood inside the top, glued to the bottom and placed to reinforce where the hinges are installed. There are also two l-sharped brackets screwed into the piece of wood, supporting a canvas panel against the open lid.
