Our Mint No. 9, a deceivingly simple blend, required two years of development. Blending wintergreen, peppermint, spearmint, sweet fennel, and additional essential oils, it has a well-balanced character. And it was worth the effort - this recipe has not changed and is still one of our most robust and long-lasting blends. As a general rule, we like to under-promise and over-deliver - with this in mind each bottle has a minimum of a dozen toothpicks.
