A binder will now hold 126 cards if you single-load the binder (up from 90 cards) or 252 cards if you double-load it (up from 180 cards). This means the binders will now contain 14 pages.
We can confirm the price will increase because of this, although we’re not sure by how much.
The 4-pocket portfolios will keep the same number of pages as before (holding 40 or 80 cards depending on how you load them). Unexpectedly, their price is slightly decreasing.
As we all know, recent Pokemon sets are larger than ever before — Lost Thunder will be the largest set in the game’s history with over 210 cards. It seems Ultra PRO is now accounting for this, though the change won’t happen in time for Lost Thunder.
Our February SM9 set is currently unnamed but we know it’ll have 181 cards before secret rares. It seems Ultra PRO is of the mindset that Pokemon sets in the future won’t hold more than 252 cards… I hope.
