Berlin-based label PROJEKT SAMSEN teamed up with BMW to produce unisex sunglasses using 3D printing technology that BMW already use. The collaboration is part of the refresh of the BMW i Collection. The sunglasses do not require hinges nor screws so this minimizes wastes during the production process and makes it easier for the sunglasses to be recycled. The 3D printed sunglasses can be personalized online and can also be engraved. Order yours now from PROJEKT SAMSEN.
