one-(wo)man coffee

Have you seen these little one-cup coffee filters? In addition to the coffee grounds it comes with, I've just put in some cinnamon, nutmeg, garam masala, and chopped crystallized ginger and candied orange peel. This isn't really gourmet coffee (we don't have a coffee maker), but it's fair trade and from our local Aeon grocery store (store brand).

Are these only in Japan?
