The base & lid fit over the "neck" tray. The neck tray is glued into the base. The lid slides down over the neck tray & rests on the "shoulder" of the base.
Pictured is a four votive candle box with an inverted shoulder tray (wrapped in plain gold foil)
The tray functions as the stabilizing neck, as well as an insert to hold the votive candles.
Graphics on the base & lid co-ordinate to create a continuous pattern when the box is closed.
