Cone Tree Candles/ Shaped tree - Christmas tree candle | Christmas present | Pillar candles | Decorative Christmas candles| Festive table candle | xmas Crafted from eco-friendly soy wax and featuring a cotton wick. *** Please allow for slight color differences due to varying monitors and lighting environments. As each candle is handmade, each one will be unique, and air bubbles may be present. Occasionally, candles may develop frosting on darker colors, a natural effect in vegetable waxes that gives a stone-like appearance. This occurs because the wax is attempting to return to its natural form and begins to crystallize. It does not affect the candle's performance and indicates that the wax is 100% natural.
