As far as I know, everything comes from the same factories, somewhere in China or Hong Kong ...
I think the TAKARA-TOMY logo is there just like with SonoKong, but instead of Mani Limited putting their logo next to it like SonoKong, they just put a sticker on the back of the package. When you see the SonoKong logo next to TAKARA-TOMY's, you know that it is from SonoKong, but in this case, with Mani Limited, it is less visible.
