BCW Gaming Box: Prime X4 XLLike the original Prime X4, the larger XL version has four cells to hold cards. The Prime X4 XL will hold four decks of 100 double sleeved cards. A pad under each deck makes it easy to get your finger under the cards when removing them. Dividers can be removed allowing you to store double size Commander or Planechase cards, and the dividers can be stowed in the back of the box if needed. Extra spaces in the back are great for tokens and extra cards.
