Golden beyblades

So I bought these years ago. These are golden variants of beyblades I bought in the stores way back. They feel the same as the original ones and needed to be assembled in the same way.
Even came with quality launchers (forgot to post those).

So yeah any ideas on this. I love them but don't see to find much info on them.

Well they are just SonoKong's golden plastics Beyblades. Their particularity is that the pieces are moulded differently, so they do not fit with other companies' Plastics.
