Candles come in a variety of shapes and sizes. Some are long and thin, while others are sold in jars. Some have unique designs that can only be possible with the use of a mould. If you plan to make candles at home to sell to your neighbours, you need products that cater to a vast clientele. This is where silicone moulds come in, and while you can use metallic moulds for the same purpose, there are clear benefits of using the former.
