Kinda love this little thing! A painted, cast metal "cage" (basket?) with a molded resin "coals" insert (that has a hole pre-drilled in the base for inserting the tiny light). See photos below.
Note: this arrived with bare wires but we soldered on the 12v dollhouse plug.
Also note: this is smaller than the center space in the Narrow Victorian Fireplace but could be used as a fancier option than the Fireplace Basket.
This set includes the metal basket (painted black and gold) plus the resin "coals", and the light wired to a 12v plug (see below for converters to use with a 9v battery).
Overall 1-3/4" tall x 1-3/8" wide x 3/4" deep.
