NAC-699 Graphite is long lasting, needs no pre-heating, is rust free and will not stick. Specs: 5.5" x 3" x 2" Tall, with (2) 2.0" Top Diameter x 1.5" Deep conical depressions.
One of our illustrious ground shippers dropped a box of beautifully machined conical molds, resulting in chipped and damaged edges. The molds are still perfectly usable but not as pretty. Since the damage claim was rejected, our loss is your gain.
