Design , sustainability , confort & very practical
It has an intelligent design, very aesthetic and practical, it fits in any flat backpack, and also keeps the temperature well, all of this even helps to avoid consuming more plastics, although it would be very interesting to have it in recycled glass or other fibers such as coconut, corn and materials alternatives such as recycled plastics from the sea. I hope to be able to have the aluminum version soon and perhaps I would consider a larger capacity A4 format. It is a great acquisition. Thank you
