Each candle is filled with dye-free soy wax with 2 wicks. These come scented in lavender infused with natural essential oils, including lavender, orange, lemon, and cedarwood. They are strongly scented and made to fill a room with scent without even lighting. When the candle is gone, just wipe clean with warm water and decorate as you please. It's the perfect size to be repurposed as a planter for succulents!
