Created with natural essential oil-based fragrances, this candle is richly optimized for a 90-hour burn time. The clean-burning soy and paraffin blend is formulated so that the fragrance evenly fills the room and the wick is 100% cotton/ non-chemically treated. Each hand blown vessel is artisanally crafted (approx. 4″ x 4″) and can be re-purposed to live on long after the candle is finished. Art glass will have slight differences of size and color from piece to piece. This is normal and assures you that this is a hand made product.
