Sometimes you can find these kits on eBay, and I bought this one a few weeks ago for about US$2. It was originally owned by a fellow in Texas, and two of the pieces were missing and one had been used. However, some of the packages were still unopened and the booklet was clean.
The bright red thing is a model of a car body made of polycarbonate plastic. It's so cool, with a real "metal flake" treatment to the plastic.
On the top right, there's a plastic shoe plate, the kind you can use to keep your heels from wearing down. The bag in the middle right contains tiny beads of polystyrene, the kind that puff up when you heat them up. The white polyallomer "living hinge" at the bottom right can flex for years without damage. More fun!
