KeepCup, a professional portable coffee cup that subverts the traditional concept, originated from a pair of siblings from Australia, Abigail and Jamie Froseth. I am worried every day when I see a large amount of no-rinse takeaway cup waste generated by takeaway coffee; not only are these no-rinse takeaway cups unable to be decomposed by the earth's environment on their own, but the trees and supplies must be cut down every year to make no-rinse takeaway cups. Paper quality is even more difficult to estimate. So the siblings started encouraging customers to bring their own to-go cups when taking out coffee. Since the capacity and materials of take-out cups are uneven, in order to solve this situation, the second sister and brother, who are professional baristas, thought about it and decided to create a professional barista that combines environmental protection and fashion concepts from the perspective and needs of professional baristas. The portable coffee cup, KeepCup was born!
