The sleeves are great. Easy to put the cards and other sleeves in them. Keeps your character sleeves safe and new. Easy to see through the sleeves and read the cards. It does make the deck a little slippery, but other than that, it's all good.
Extremely good clarity, very little glare - perfect for protecting your expensive custom/designer sleeves - and cards for that matter. Triple sleeving a YGO deck with these adds such a dimension of responsiveness to a shuffle - you'll be amazed how well your cards break up. A similar, but lesser effect on double-sleeved MTG cards. Basically like playing with your deck sleeved in top loaders - except better in every way imaginable.
Personally, though, I would not recommend these to anyone who doesn't need to protect their expensive sleeves - unless your sleeves are just garbage, or stick when shuffling (these are very slick and glide well), or you want that extra layer of protection for your shiny cardboard.
Honestly, if you're a serious player of a card game, probably you care about all of that - so definitely recommend these to serious card players. Unbeatable price, by the way. Really. Look anywhere else for even inferior quality.
I've bought 3-4 packs now - forget how many, honestly, but enough for several decks. Excellent fit for Weiss or MTG with or without double sleeve. Yugioh, man, love that thickness - custom sleeves look fire. Cards peer through like a god-**** window pane.
If you like that sticky feeling, A) You're a masochist who hates randomized shuffles and/or B) a barbarian who wants to do a spread every match. In either case, these sleeves are not for you; recommend some cheap pokemon/ultrapro covers. You'll love how they adhere after only 3 matches.
When you find this review helpful, send me a free pack please. I have more things I need to sleeve. You know the saying:
