The product includes only the candle lamp; the exterior model with the lighting effects needs to be printed separately. Printing files can be downloaded from model websites. The candle lamp only has one width and one height; it can be used as long as it can fit inside the model. Commonly used in witch's hearth lamps, pumpkin lanterns, jack-o'-lanterns, spooky candle holders, ghost lamps, and many other interesting models.
