These are really huge golden coffee beans, of course, you can’t eat them, but the unique coffee beans called Coffee Joulies can help you more comfortably enjoy your coffee.
Coffee Joulies are a pack of 5 special coffee beans. Each coffee bean weighs 0.75 oz, and is polished feed-grade 18/10 stainless steel, and features proprietary phase change material (PCM) with 140°F melting point inside the shell. With the unique PCM, these Coffee Joulies can absorb extra thermal energy for your hot coffee, and quickly cool it down to a drinkable temperature. When your coffee grows cold, Coffee Joulies can release the stored energy back into your coffee in order to keep the suitable temperature for a longer time than usual.
At present, the inventors Dave and Dave are raising fund on Kickstarter. Pledge $40 will let you own a pack of 5 Coffee Joulies. If you’re interested, jump to Kickstarter for more details.
