I'll list all the details I can recall from my memory:
- This is a product from Japan/Korea. I bought it from a local stationary store (~10 years ago). Similar products of this type looks like this (http://www.kidstoyo.co.jp/item2745/)
- The pack contains colored SQUARE sheets of the same dimension(about 15*15cm) which some are of plain color while others have patterns (or crease guide lines) printed on. (you can get the idea from the link above)
- Judging from the patterned sheets, the models resemble a mix of racecars and spaceships. I remember one looks like an F1 racer
- Interestingly, the models are named after the planets of the solar system (Mercury, Venus, Jupiter, etc.)
- The instruction sheet is a long piece of paper,which the back of it printed a race track
- Apart from the racecar models,there is also a guide for "origami spring" that can help push your model forward when you are racing it on the track just mentioned
Thank you very much for your time!!
