Enjoy your hot drink or smoothie on the go! Easy to drink through the drinking opening in the lid. KeepCup Brew is available in Small (227ml + Medium 340ml) And in many fun colors. When the cap is off, this is also the ideal cup to use all day at the office. When you travel back home, fill it with hot tea, put the cap on and enjoy a hot drink on the go in the car or train. KeepCup was founded out of love for the environment. All the coffee-to-go in disposable cardboard cups creates a huge amount of waste. Every minute, more than one million cardboard cups are thrown away worldwide. Since June 2009, more than three million KeepCups have been sold, saving billions of disposable cups. KeepCups are now sold in 32 countries. KeepCup has offices and production facilities in Australia, the UK and the US and is supported by 25 global distribution partners. KeepCup believes in creating a better world together through reuse and in starting a re-use revolution together.
