Tired of burning your tongue on coffee only to have it get cold a few minutes later? With the Coffee Joulies Gift Pack your coffee will be ready to drink in minutes and will stay that way for hours. Each polished stainless steel shell is filled with a special phase change material that melts at 140°F. Put them inside the custom-printed thermos and they absorb heat from your coffee when it is too hot and release it back into your coffee to keep it at the perfect temperature
