Ecolect, a great sustainable materials resource, has created their GreenBox. It’s a subscription to eco-friendly material samples so you can check out physical samples of materials you might want to make something with:
Every 3 months, we release a sampling of 12 cutting-edge materials, packaged in a durable box that can also function as a catchy display. The criteria is that the materials must be innovative, environmental solutions ideal for design, engineering, and marketing teams. The chosen samples will highlight trends that other material producers are setting, and serve as inspirational and informational reference for you when initiating new projects. After an entire year subscription, your studio will have their very own eco-materials library of nearly 50 different products.
