This is the best quality sleeve pack you can have! I like the clearish ones because it is much cooler that way. I don't like the sleeves with pictures on em cause i like to see the backs of the cards, just like in the yugioh cartoon! I have seen cheaper packs of these same sleeves though. In San Francisco,California's chinatown, this SAME ultra pro sleeve pack is only $3.99! i don't know why its $6.00 something on amazon, because chinese places sell things cheaper. I know because im chinese :) THESE SLEEVES ARE AWESOME AND SO YOU SHOULD BUY IT IF YOU DONT LIVE NEAR A CHINATOWN WHERE THEY SELL THESE FOR 4 BUCKS, AND ISNT BOTHERED BY THE FACT THAT YOU ARE GETTING RIPPED OFF BY 2 BUCKS! When i say "ripped off", i don't mean these sleeves are bad AT ALL (they are the best you can have), its just that its 2 bucks more than the ones i can buy in chinatown :)

Very good quality, I have some really thick LP Jackets, with 3-4 LPs inside, and they fit easily inside these sleeves.

The sleeves are made of a very durable material. They stretch and zip up with a very strong feeling. The zip takes a little getting used to, but once you get it it stays put. Fantastic product and i definitely plan on buying more.

These are of good quality, and the paper is not too thin. As I continue to "dig-out" my LP collection, these have been a great asset to replace the torn and tattered sleeves from the 1960's. I would highly recommend this product - and plan to order more packages.

In the past few years I must have bought 5 or 6 different types of new inner sleeves, and of course I continued using some of those sleeves that had come with the record. I have to say that these MoFi sleeves are simply the best in terms of protecting the records, while keeping the static away. I am not sure how they do it, but it's just a fact - slide a record in and out, and somehow it DOES NOT end up covered with dust ... pure magic :)

Also, the corners resist crinkling a lot better than some other types, which is probably irrelevant from the point of view of the record safety, but is certainly more pleasing aesthetically.

If you need to double sleeve your Yu-Gi-Oh! cards, look no further. This are THE greatest sleeves you can purchase. They are crystal clear and fit tightly around the card, but not enough to bend it.

If you want sleeves that perfectly fit magic cards, these are as good as money can buy. They will "perfectly" fit the card, so you could damage the top if not perfectly in the sleeve. I use these to double sleeve cards so my cards are near mint even after a season of playing with them.

This is a must have if you play EDH or a Cube. Ever play with an idiot that can't keep food or drink off a table? Now you never fear your cards dying to that moron.

Dragon Shield sleeves are the best sleeves I've used. Good, high-quality sleeves. Petrol is a cool color too. kind of a dark blue/green or dark teal. I use them for MTG.

I love these so much that I've ordered more and more and put my cards in these and threw out my old sleeves. Honestly I wouldn't buy anything else, these are sturdy and well worth the price.

Top quality sleeve. I could even take it from my iphone and attach to an android after 3 weeks of use. I use it to hold 3 cards and a bill

Best sleeves available. These last me forever. The only reason I ever need to replace them is if I want to change up the color of my sleeves. They hold up well to shuffling and frequent use.

The sleeves are great; and even fit in my wallet.  I can actually fit 2 bank cards in one sleeve.

These sleeves work wonders for PROTECTING your cards. Pokmon, Yu-Gi-Oh, MtG; these guys have all the sizes and colors you'll need to separate your Main/Side/Extra decks and look good doing it.

NZXT is definitely a high quality manufacturer. I've sleeved cables myself as well as purchased pre-sleeved cables. These are the best quality i've found outside of my own work.
I've actually resorted to buying them for most of the builds I've made for local friends. They cut down the sleeving time drastically and really clean up the case.
