Hi! This is a noob question regarding the protective card sleeve blue box noted next to ANR products. What does the number in the grey middle box mean.

For example, next to the Opening Moves product pic, there is blue box with the number 2. But, in the pane on the right, there's another blue box with the number 6.

Could someone enlighten me, cause it's Burke Bugging the hell out me.

This indicates how many packs of sleeves the product will require, and which ones (gray indicates standard card size, used by Magic and other CCG/LCGs). Each pack is 50 sleeves, so if you do not purchase FFG branded sleeves, it is still useful in determining how many you'll need of whatever sleeves you decide to purchase.

In that specific example, I believe that the 6 is talking about the Core Set, whereas a Data Pack always requires 2 (with 40 sleeves left over).

Thanks for the quick and very understandable reply, Shadin!
