10 gloss shrink plastic sheets from the collection Surfacez by Sizzix. In black.
Shrink plastic is made of plastic, where you can cut, stamp, draw with permanent pens even print designs.
After creating the shape you want, use your heat gun or an oven, heat it up, and it will shrink and become hard and solid, always keeping the shape you gave it in the first place.
After baking, your object will be about 40% smaller than the original size.
