We blended the warm fragrance of orange essential oil with the woody fragrance of kuromoji and Siberian fir and allowed it to slowly penetrate into grape root. It has a sweet, warm fragrance that brings peace and calm to quiet winter nights. Kuromoji is a tree that has been valued in Japan since ancient times for its fragrance. Lavish kuromoji toothpicks are still used today with Japanese sweets and at high-end Japanese restaurants.
