ROX are the perfect way to bring your beverage to its ideal drinking temperature and keep it there without watering down your drink. ROX are made from 100% Soapstone, a non-porous, odorless, and inert stone that will retain a neutral taste in your freezer, unlike ice cubes. Soapstone has a high thermal mass, giving it the natural ability to retain its temperature for extended periods of time. For Centuries, people have been using soapstone to cook food and keep warm. Now we’re using these stones to keep cool. As Bob Dylan would say, “Times they are a changin”.
