Korean vs Japanese Ultra Shiny Boxes?

Ive seen a ton of Korean Ultra Shiny boxes pop up lately and am wondering if anyone knows the pull rates on Korean? The boxes are much cheaper and have 15 packs per box so Im guessing that theres some sort of catch with pull rates.

They do not have a gx card in every pack

Does it still follow the guaranteed three shiny cards per box? if not about how many would someone pull per box?

i think it still has the three shiny cards, havent got mine yet still on the way. just look up korean gx ultra shiny on youtube to get a better idea.


i just got my korean shiny gx in the mail, each pack has 8 reverse holo cards and two holo cards, i got one normal gx and one prism star which replaced one of the holo cards in the packs, and i got the 3 shiny cards and i believe i got lucky and pulled a full art trainer as well. im pretty happy with this purchase and will be buying more

also worth noting is that these cards have the yellow boarder instead of white as well as an english back.
