You are buying the cone shaped tin inserts ONLY. We carry two types of sugar mold tin inserts, the cone shaped, and the flat bottom inserts. Our sugar mold candles fit both inserts. With these cone shaped inserts, our candles fit perfectly snug and flush. If you prefer the candles to stick out above the wooden mold, then the flat bottom inserts are for you and are better for burning votives. Our candles when used in these flat bottom inserts will stick out of the inserts. We will list both types of inserts. They are tin and copper color. Not using an insert when burning candles in the sugar molds is asking for trouble. The problem with glass inserts, which we do not carry, is that sooner or later they will shatter and, well, create a mess and a danger. Not using the inserts will make it almost impossible to dig the old candle out of the mold. All of our complete sugar molds come with the inserts. Dimensions: 2.75"D x 2.5"W. These are not food safe and not recommended as molds to make actual sugar.. They will also NOT hold water for long periods of time. The last photo shows how our candles fit in these "cone" inserts...flush..
