Glass Mug Gift Set

Coffee & tea drinkers will love our scientifically-optimized hot beverage experience. At home or in the office, every sip is perfect, from the first to the last.

  1. Our double-wall glass mug insulates much better than normal ceramic mugs. We use glass that is 50% thicker than other glass mugs for improved durability.
  2. Our silicone lid traps heat that would evaporate through the open mug, and also prevents spills on the walk back from the coffee maker.
  3. Coffee Joulies absorb all this well-contained heat, quickly cooling the beverage to the perfect sipping temperature, then slowly releasing heat back into your drink to keep it in the ideal temperature range longer.

This works over and over with each cup of coffee poured, creating the perfect sip every time. No need to freeze or recharge Coffee Joulies between cups. Plus, they literally last forever.

Includes 5 Coffee Joulies, 1 Glass Mug & 1 Lid.

    Coffee is too hot
    Use Joulies to cool it down
    And keep it perfect

    Tired of burning your tongue on coffee only to have it get cold a few minutes later? With Coffee Joulies™ your coffee will be ready to drink faster and will stay in the perfect temperature range longer. Each polished stainless steel shell is filled with an advanced phase change material that melts at 140°F. Put them in your coffee and they absorb heat when it is too hot, storing that energy inside. When your coffee reaches the perfect temperature this stored heat is released to keep it there longer. The 5-Pack works with up to 20 oz of coffee, one bean per 4 oz.

    Coffee Joulies™ Set of 5 include:

    • 5 Coffee Joulies (made in the USA)
    • Instruction card
    • Joulies logo carrying pouch (optional)
    • Available worldwide

    Booze Joulies

    Whiskey? Vodka? Tequila? Yes please! Keep your booze cool this summer without watering it down with our new product, Booze Joulies. Booze Joulies are stainless steel shells (just like Coffee Joulies) that contain a proprietary blend of food-grade liquids that freeze below the freezing point of water, making them literally colder than ice. Leave them in the freezer for a few hours and they're ready to go. Use them in a shaker to cool a drink before serving it up, or pour your favorite Scotch over 2-3 Booze Joulies in a rocks glass for perfect sipping.

    Booze Joulies™ include:

    • 6 Booze Joulies (made in China)
    • Booze Joulies logo carrying pouch
    • Gift packaging with instructions
    • Available worldwide

    Thermodynamic "stones" keep coffee at the right temperature for hours.
