Give all your cards a little extra protection. This add-on includes enough high-quality sleeves to cover the cards in Return to Dark Tower and the Alliances expansion. 110 standard card sleeves and 85 mini sleeves (plus some extras for lost or broken sleeves). Most sleeves will have a custom print, but some standard-sized sleeves will be completely clear to accommodate the double-sided cards.
