Gel candles are quite different from standard paraffin or soy wax candles, they can't stand on their own & so they need to be held in a glass or heatproof container. The benefit of this though is that you can add all sorts of beautiful embellishments, such as s&, glitter, marbles, or anything fire proof! This kit comes with a selection of seashells to get you started. The gel is not only transparent but it also burns almost twice as long as a standard candle making impressive decorations that will shine evening after evening. The kit will make four candles with the glass containers included, & there's a little extra gel wax to spare for you to get creative with your own ideas.
