Hmm. We like the idea of these reusable stone cubes, made from "Swedish pollution-free rock." You put them in the freezer for an hour and they keep a drink cold without diluting it. On the other hand, they kind of look like dirty blocks of ash. We're torn.
These rocks are made by Mocha in the UK. You get ten cubes that come in a leather pouch- fancy.
