Eitaro has been crafting traditional Japanese candies for over 200 years, and they have produced this candy flavored with shikuwasa AKA shiquasa. Shikuwasa is a tiny, sour, and green citrus fruit that's similar to a lemon. They are typically grown in Okinawa, an island in the south of Japan. These hard candies are vegan, gluten-free, and made without artificial colors or flavors -- just pure tangy goodness that will make your mouth pucker.
