This is 15ml (half fluid oz.) pure, uncut peppermint essential oil. Our peppermint oil is from Japan, where we found some of the best, brightest, most refreshing peppermint oil comes from. Since this is uncut essential oil, go easy, it's quite powerful. There is a dropper insert in the bottle to allow for easier application. Since we buy in quantity and fill our own bottles, we can offer this amount at such a good price.
