I received this as a novelty item from Low Classic. It's a Salt Rain travel set, including 30g of toothpaste, a toothbrush, and a dedicated pouch. The toothpaste has a sparkling limited-edition design, making it very cute. Perfect for travel or for brushing your teeth at work! Salt Rain is a lifestyle brand that develops care products incorporating minerals from "Doban Salt (Gray Salt)," a precious salt produced in very small quantities using the traditional salt-making method of Korean tidal flats.
