These capsules are used with the Delonghi Lattissima espresso machine. Unfortunately, Nespresso (Nestle), is the only place that we can seem to find these capsules at currently. They come in many different flavors, and you can buy sets of only a specific flavor. The machine actually comes with a booklet explaining the different flavor types found in the capsules. My personally favorite is the Volluto which is "delightfully sweet", but every person has their own preference :).
