With this kit, one can cast natural soy candles in beautiful oyster shells. The kit comes with all the materials and instructions needed. If you could do with a little at-home indulgence time, try this Mini Craft Kit for candle casting. Use oyster shells and soy wax to create the finest candles for one's home. The soy wax is 100% vegan, burns cleanly and soots far less than traditional candles. And the oyster shells have a beautiful, organic shape that fits perfectly with current interior design trends. If you find it hard to get the finished candles to stand on their own, simply try placing a couple of silicone dots under the base .
