The girls set limits on how many Limited Edition sets they'll sell in order to save their wrists, but otherwise there's a window of a few months for people to place orders and pay for them and then at the end of that Cover goes to the supplier and says "We had 4379 orders, so please produce 4500 pieces" (the extra being to cover breakage/replacements or whatnot)
If there's only 250 orders, they only place 250 orders. If there's 1700, they place 1700. Once the pre-order period ends, they stop accepting orders and then it is permanently out of stock unless for whatever reason they decide to rerun it (or you buy it from a reseller on Mercari, etc)
