If you're wondering what size binder you will need for a White Flare Master Set with no cards stacked on top of eachother, we recommend a 12-pocket binder with 480 pockets. 

 

Here's the set breakdown:

• 80 Numbered Base Cards

• 80 Reverse Holo Base Cards

• 80 Pokeball Reverse Holo Base Cards

• 72 Masterball Reverse Holo Base Cards

• 6 Base EX Cards

• 88 Secret Rare Cards

In total, a complete White Flare Master Set contains 406 unique Pokémon cards.

If you are combining Black Bolt and White Flare into one binder, you will need a mega capacity binder.
