In and of itself, I think the idea is great and was surprised that there are already as this offer. 3 euros extra for a bad self-adhesive photo printing, you must stick itself, but I find a lot of nerve. Especially since the signs are just a few millimeters in size and who is a bit clumsy, has only snippets.
Overall, I still think it's a funny idea. Would not but wish that the model car will also come as ready and the quality of the print is perhaps a little better.
