This is shavings from a kaya tree. They have a slightly yellow tint. Kaya has a pleasant, sweet, and spicy-like fragrance (in my personal opinion). You can put them in a tea bag and place it in your car or room for a nice scent. They will be sent in an 80-size box. A4-size samples are also available (500 yen). Quantities are limited and will be discontinued when supplies run out.
