The picture you see above is not of some ice-cubes designed like rocks…rather, they ARE rocks for real! Originated from the Scandinavian country of Sweden, these Nordic stones are absolutely pollution-free and is by far the “the purest way of cooling your drink – literally ‘on the rocks’“. These stones not melt like usual ice and therefore can be re-used easily making them very eco-friendly.
To use them as ice cubes, just place these stones for 1 hour in the freezer. On an average you would need two or three Nordic Rocks to cool off your drink. They seem to give off cold gradually and equally. “For maintenance, rinse your stones under clean water and store them in the leather pouch provided. They are then ready to serve you again any time to your fullest satisfaction.”
Price? $23 for a pack of 10.
