Brand identity trends are moving towards more organic, eco-sustainable style of design, and, as with most trends, it's always nice to see a fresh approach to it. The brazilian design studio Dona Baronesa raised the bar with their hand-made stationary and eco-friendly materials. All their stationary is made with recycled/re-used paper and all is stamped by hand with their brand image that they have called 'Sustainable image ID'. In the end, all that skilled craft ends up giving their company an added value, there is a lot of effort behind each business card, wrapping paper, packaging, etc. and that is always a great way to get your name across, it sets you apart from the expected.
Their 'everything can be used' philosophy is executed beautifully, and creates a unique yet cohesive brand identity. Their work makes a statement about great design that can be sustainable as well. You can visit their studio and check out the rest of their work here.
