Ichiban Kuji are sets of limited merch, usually only available inside only it. Top prizes are rare and normally correspond to the A prize, from there they go through the alphabet down to the bottom prizes that are much more common. The lowest prizes will often be blind box items so that even though you may win multiple of the prizes, it is uncommon to actually get double ups.
Each ticket is sealed and if bought in store you peel it back to reveal your prize, if purchased online we will draw the tickets for you. We have no capability of knowing which ticket will have what prize so we are unable to affect the outcome or win you a specific prize, even if you win a top prize and wanted a more common prize.
