It seems these bricks were made in the late 1970s without Lego’s authorization, by rogue employees developing new types of plastic and experimenting with their molds and various plastic colors.
It is unknown just how many of these bricks were made, but they are extremely valuable, and in my opinion and many others, very beautiful.
Wouldn’t lego be best just mass producing a batch, selling em, essentially devaluing the originals by a large degree?
Edit: Watched the video, turns out they simply could just… Stop discarding them 🤣
