A bit worthless but still important to point.
Unless, I'm crazy, on top right and left, there's JY written in black on a pink circle
Yes it does says CK, but if the number is right, then it would be JY-124 or SC-124. My friend is going to open the cart and see if it has any JY id or date (when it was made).
It seems it is a late JY cart but I'm not 100% sure.
I guess some people will this a bit useless, but just to show that JY had Yuu Yuu hakusho in their hand.
