I am happy to see the keys be added to your collection. And to now have a video showing a prytotype key! I'm glad you liked them and I will keep an eye out for more.
@Notlikehawkman Yes, for all the prytotype keys that I own, the actual key part is the same as normal keys. The only difference is for the one click keys, which are cast in transparent blue.
@KaoruMzk I actually have an answer to that. According to the guy that sells them, he bought them from a toy market in Hong kong. Basically since these are essentially trash, the workers take them from the factory's and sell them at their own tiny stalls. Then the guy sells them on ebay that is how I got them.
