Sometimes we carry flat or square bags, with official documents, books, iPads, etc. neatly placed inside. At first glance, everything looks beautiful, but the square beauty will definitely be put away again. It was destroyed after entering the round kettle, and the whole bag swelled up instantly, which was really nerve-wracking.
Now someone has really heard this voice. They are a R&D and design team from Australia. Simply transforming the cylindrical kettle into a rectangular shape can solve this little trouble that has troubled us for a long time. The sizes they introduce are designed according to general paper size specifications. Currently, they are available in A4, A5, and Letter sizes, with capacities of 1.25L, 750ml, and 1.25L respectively. Its like a book, you can easily put it in your bag and it doesn't take up any space.
