NU5 by Maica Sy thermodynamic stones

NU12 IDEA#5 Thermodynamic Stones by Maica Sy I am always excited to see a variety of new product innovation. The simplicity of this product aims to help keep coffee at the ideal temperature for longer. These stones can be immersed in hot drinks— cooling them while they're too hot, and then heating them as they cool down. By using this, reheating hot beverages wouldn't be necessary anymore. <lack details>
