Add some fun to your tub without adding the crud. This aromatic blend of natural oils is an amazing way to unwind after a long day. We use Sunflower or Olive Oil as our primary carrier oil for our bath bombs which is easy on the pores and a great source of vitamin E, rich in nutrients and antioxidants. BathBombs come in essential oil options and fragrance oil options. Colorant is always clay, spice or charcoal based never artificial or mica. Fragrance oils are sometimes used in low percentages in our products. All batches are tested for fizz; however, we cannot guarantee this with each since we are unable to test every individual one.
