Made out of polished, high-quality aluminum, the ROK Espresso Maker will serve you with a warm cup of coffee through a manual, non-electric design. This eco-friendly gadget uses only power to boil the water for your espresso. You can not only use it at home but also while you’re camping or riding a boat. The lowering of the lever arms will help you achieve the right pressure required to prepare the espresso. This trapped air then forces water through the ground coffee at a high pressure. A mechanical approach to preparing coffee you can enjoy anywhere on the go. An environmentally friendly manual espresso maker, it has durable engine-grade metal guaranteed to last at least 10 years.
