Your records deserve the best.
Definitely the best inner sleeves you could get. Not the cheapest though, but if you consider the price of a 12" and want to protect them, that's worth the investment. Even though they're square, the paper layer makes them solid enough not to fold when you put it in the outer sleeve, as opposed to most poly-only sleeves - which become less appealing as time goes by. It also gives a nice touch as the record strikes out better visually. I keep this together with the original sleeve in most records (except when it's a simple paper one), and both generally fit well, while the record is still not too thick and fits in standard outer sleeves (Blake sleeves). And of course, it protects the record well, avoiding dust and static, plus paper scruffs etc.

Audiophiles Delight / Great for OCD
These are brilliant for protect your records from getting brushed and scratched and also significantly reduce static. They are very thin which means you can usually get away with putting them inside a paper inner sleeve for added protection. They have a three layers a clear front and two layers on the back which holds a thin paper insert to give the sleeve some support. The added support means this sleeve keeps its shape very well and you can very easily slide it out of the records outer sleeve. It also makes sliding the record in and out of the sleeve very easy and this can be done with one smooth action. I would highly recommended these sleeves especially for those of you who collect rare and collectable records.

Archive-quality for your peace of mind
Without a doubt the best inners money can buy if you are looking to protect your records from deteriorating due to contaminants, low quality plastic inner sleeves sticking to the record (I've read that this has happened to some people), or paper inners scuffing the surface of the record. The material that touches the record in these inners is high-grade and designed to never stick to your vinyl even after many years. Look into Mobile Fidelity Sound Labs to see this company's extensive history of high quality products. I replace plain paper inners with these after cleaning my vinyl, even if the paper inners have polyethylene (PE) lining - the quality of the PE in the MFSL inners is much higher than that used in inners from the 70's (which is when a large amount of my records were pressed). Also, old inners can be full of contaminants; why reintroduce these to the clean vinyl? These would not fit inside a lyric/picture inner, so I use Nagaoka type inners for those, but you could use these and keep the original inner separately inside the sleeve. Others use Nagaoka inners on their own (without putting them into the original inner sleeve), including a friend of mine, and from experience when playing his records I find it very difficult to re-insert the inner into in the sleeve. The paper sandwiched inside the back of the MOFI inners allows them to hold their shape, which makes it a breeze inserting record to inner and inner to sleeve.

Very high quality and fit well, a must for keeping records clean!
These are awesome and a must if you want to keep your records safe. Clearly very high quality, they are very well made and feel extremely durable (the plastic bit is so soft), I notice much less static and debris on my records when they come out of these. They fit easily in all the paper artwork covers I have, no idea why people say they don't, minimal wrinkling (it can be gently worked out quite easily). So much easier to pull these in and out of covers and very satisfying to know your records are well protected. Expensive but well worth the money!

Good name for a good reason
First may I begin saying Mofi is an old Company. I am not sure how old. but as I was a child growing up in the 80's I recall I have seen Products of this Company. but was too young to purchase anythign other than cheap records :) Anyway - Mofi have been around since at least the 70's and are considered of the Top 10 in the market up to now. The sleeves, when they came to me, have been compared to those of another Company I bough from, and I immediately seen the difference. The sleeves are thick, but as I noticed i put one dirty LP and the dust has been drawn inside and the LP when i took out wasn't as dirty as before. Of course I didn't continue wit this experiement because it's no idea to put dirty LP's inside a New expensive sleeves. But just to show IT IS indeed a good Product. There was other reason that made me be sure I want to purchase it once again. It is the name. They say a Product that has a good name for so long isn't likely to become a bad one. The best artists around use Mofi Products. I think to me it's enough to be content With what I bought and i strongly recommend it

Easy to use and good protection
The quality of these are nice, especially in their ability to keep the records in prime condition. For some album covers I found them a little bit too flimsy to easily slide them in, making them fold slightly in the corner. The look of these is also pretty dull, and I would've wished for them to be a bit more anonymous with less printing. Sliding the records into them could however not be easier, with much less friction than the records original sleeves. They do also seem to be very good for my records, keeping static and dust away, and in the end that's what matters the most.

Great Quality
Came earlier than expected. Really good quality and price. Nice presentation although it would've been nice to have slightly more secure packaging for the sleeves and slightly stronger corners.
