The elementary core of the The Bauhaus / Ucon Acrobatics Collaboration is an innovative material. Cork from Portugal is cut into thin layers and then fixed to a silver waterproof film. In the final step, blue paint is applied to the cork surface using a rubber roller. The unique structure of cork, with its jagged textures, allows for a unique artistic composition.
