Card sleeving is the standard kind of protection in all card games. To increase this protection most players add a smaller, inner sleeve (sleeve-within-sleeve) to seal their valuable cards from all sides. This Double Sleeving Pack contains both inner sleeves and regular sleeves to provide a maximum of protection for up to 80 cards. Inner and outer sleeves match perfectly to make double sleeving fast and easy. Both sleeves are extra clear for perfect visibility with unaltered colors or contrast of the contained cards. The back side of the black, regular sleeves is 100% opaque and provides a great shuffle feel.
