“Rocks” are a luxurious version of the Nordic Rock Ice Cubes that I posted about a while back.
The stainless steel cubes are chilled before being added to the beverage. “Rocks” control beverage temperature between 15˚ and room temperature depending on the number of “Rocks” used. The product adds a luxurious weight to the glass and will not over chill or dilute the beverage as ice does.
Get them here.
