Our refills are made from European-grown soy wax and scented exclusively with essential oils. Entirely plant-based, they offer a clean and harmonious combustion. Each refill is hand-cast in Provence, France. This 250ml candle refill has been specially designed for use with the OCTŌ Refillable Ceramic Clay Pots. Each refill measures approximately 70mm x 70mm x 70mm and fits neatly into our reusable container. The refills are packaged with recyclable materials and without plastic as much as possible, in a more environmentally friendly approach. You can also order our refillable starter kit, including the OCTO's reusable ceramic pot. At OCTŌ, we carefully select each material to limit our impact on the environment, from ingredients to packaging.
