Why not 3D printing it ? Easy to carry, no maintenance, easy recycling, cheap mass production. Well, it requests a certain investment, but there are facilities, where you just leave the design & they do the job for you. Further more, you have all the color choice from yellow over golden & red to green (!), blue, brown & black, not to forget pink. Think about that method.
