These sleeves, like all other Dragon Shields, are high quality and will protect your cards through the worst of play conditions. But unfortunately for some, the transparency of the back of the sleeve can make a big difference as some tournaments will not allow transparent sleeves. These sleeves are unfortunately quite easy to see the back of the card through, and would not be tournament worthy without a second product called ‘Dragon Shield Smoke inner sleeves’. Still great looking sleeves for casual play.
