MoFi Original Master Sleeves help preserve your most prized recordings. These custom-designed inner sleeves protect against scratching, static build-up and contamination; all common problems associated with regular sleeves of all types. Your records are irreplaceable. These sleeves will guarantee they last a lifetime.

These are imported, three-ply, anti-static, premium sleeves (similar to rice paper) and work with both LPs and laser discs. Back construction consists of a paper layer sandwiched between two sheets of high-density polyethylene (HDPE) with a translucent HDPE front.

Needle Dr reviews the MOFI Original Masters inner sleeves
Collecting vinyl is a hobby that can lead you to the craziest of places. Antique stores, book shops, and yard sales are all places to find some of the best music out there. The downfall of finding hidden vinyl gems is often times the record sleeves. Scratchy paper, wrinkly plastic, or having no sleeve at all can be detrimental to the record, so having some nice inner sleeves on hand is always a good idea. There's no question that the Mobile Fidelity Original Master inner sleeves are the best on the market. They're safe, and protect the integrity of the vinyl more than any other sleeve out there. Highly recommended.

Protect your records with MoFi inners

Reviewer: Nick
I’ve been using MoFi inner sleeves for my records for many years, and they are a perfect way of protecting your investment of vinyl records. After all, you want them to stay in the best possible condition for playback. Not to mention, the value of certain records can be or become rather high, so you obviously want to keep them in great condition for many years of listening pleasure. As many record collectors are aware, regular paper inners can eventually cause scratches after putting them in and taking em out of them, and MoFi inners are a far superior alternative to paper inner sleeves.

Bought these? Check your records!

Bought a pack of these a few months back and just noticed smudge marks all over my vinyl caused by the inside of these sleeves. After searching online I noticed this issue dates back to 2012 with MOFI sleeves( Looks like a have a lot of work to do cleaning about 40 records. Please check your records folks. Unacceptable!

Life is too short, and my records too precious, for cheap, flimsy record sleeves. Kiss your static good-bye.

These are the best.

They are really made out of the perfect material to slide in and out of your record jackets. I love these, and they will cover every single piece of vinyl I own, from now on. I have bought three packs.

Two great things about these sleeves--no static electricity, they're roomy enough that they don't scrape the records and they have arrows showing you where the opening is. OK, three great things. I happily use them for all my records.

These are a MUST!

These are absolutely necessary. Anyone with a good turntable who keeps their records clean (as one should) should 100% purchase this or something just like it. They are priced very well too.

I typically did not like flimsy inner sleeves as they are so hard to get back in the jacket! But these work and even allow me to leave the original sleeve tucked into the jacket as well. The anti-stat properties seem to be for real too. I am retro-fitting all existing albums as I play them and all new records get them automatically.Especially important for old flea-market and other used LPs - don't put your cleaned records back in those nasty jackets. At 40 cents per its a good investment.

Fine product

For sure, much better than what the lp´s usually come with. They cover the record completely and just feels good as I take the record out/in. Overall: increases my satisfaction playing records!

I have far less static with these then any other inners I have used. They are wafer thin which helps returning vinyl to the jacket on some of those tight fits.

The best!

First a clean on the Okki Nokki and then into a MFSL sleeve. I've been using these for several years and see no reason to switch. First rate sleeve in my opinion.

Yeah, what they said .......

These are great sleeves and well worth their cost. Got my first 50 to try them out, and will continue to buy more. LPs slide in and out of these sleeves with the greatest of ease. This is a great sleeve to use after you've cleaned your vinyl. They will remain static free. Awesome find.

No complaint !

These are great because they are so thin; I can leave the original inner sleeve in the jacket while using these. One thing to consider is that the center label is only visible on one side; doesn't bother me though.

These are tops in protecting the record, but what a headache getting it back in the cover. Often the thing folds and gets stuck...forcing one to grip the record harder than you want to, and after making several attempts at at a clean insertion, you might long for something more...rigid. So, the extra manhandling may negate the fine record coverage.

Absolutely the Best

You will not find a better inner record sleeve. I liked these sleeves so much I just ordered 2 more packages. They cover the record completely and are easy to use.
