You are buying 6 flat bottom inserts. We carry two types of sugar mold tin inserts, the cone shaped, and the flat bottom inserts. Our sugar mold candles fit both inserts. The flat bottom inserts are better for burning votives. And the candles will stick out about an inch above the flat insert. Our candles will fit snug with our cone shape insert that we have listed separately. 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 can be dangerous. 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 tin inserts.
