The white shells were used for JP rental carts.
However those shells do not look the right white color of rentals. i belkieve those are custom shells, probably made by the same company that does the yellow 161 shells. Regarding the labels, they are custom and probably used the ones in jamma-nation-X as a base but I totally like them having the name in both languages.
Regards.
It is possible to buy these custom shells?
I've also contacted the author of the video to ask the label template (still no answer...)
The dual language labels are pretty classy.
