This double sleeving pack contains both inner sleeves and regular MATTE sleeves to provide everything a player needs to protect up to 100 standard sized gaming cards. Card sleeving is the standard kind of protection in all card games. Inner and outer sleeves match perfectly to make double sleeving fast and easy. The matte front blocks annoying reflections at the sleeves, to ensure that the card is visible from all sides and avoiding symptoms of eye fatigue during gameplay. The back side of the black, regular sleeves is 100% opaque and provides a great shuffle feel.
