Mobile Fidelity Sound Lab - Original Master Record Inner Sleeves (50pk) - MOFI MFSL

I bought these a year ago January via Amazon as part of a larger order of items as I needed some decent album liners to replace worn out paper ones that come with most LP's and knew they were of quality. What I like about them is simply the fact that there is rice paper in between sheets of the poly on the back side to provide support/structure to the sleeves so they can be inserted into the album covers much easier. They don't leave anything on the LP's nor do they produce static as I do not get any additional static or pops/clicks from using them on my LP's but then again, I don't live where it's excessively dry during the winter months so that helps. Overall they have been great in day to day use and will happily buy more when the time comes. Since I had originally purchased the original package in 2016, I find these still a pleasure to use and fit the LP inside their outer covers just fine. The one thing I'd change is rounding the corners, especially the bottom ones so they can insert into the jackets a bit easier. Otherwise, they bunch up in the corner but DO protect the LP's from swirl marks (or any additional ones if the LP is a used purchase and has some swirls already). Any new LP that comes in a paper sleeve also gets one of these to protect it as I play the album, taking it out of the jacket to play. LP's fit nicely inside and the rice paper insert does make the otherwise very flimsy poly inner sleeves easier to handle to insert/slide out the record and to insert into their outer jackets. So far they have held up well, not split or anything else and had finally used up the original pack a while ago and finally got around to buying another pack of these MOFI sleeves as I've purchased additional LP's and some older albums I've had for a good while are now in dire need of new inner sleeves so without hesitation, bought a fresh pack of these and they have arrived literally in 2 days from purchase. All in all, still recommend these if you desire to protect your LP's from daily use.

Fantastic product! I like the microfiber backing on the inside of the sleeve. Very well made. I have and will be buying more. Quality product. Totally recommend!!!!

Best inner sleeves

Great protection for my vinyl collection. Most of my records came with mediocre quality sleeves, and my older collection are simply falling apart. Now when I listen to an album, I give it a good cleaning, and replace the sleeve. It is thicker and heavier than a cheaply made paper version, but these will last and protect much better. If the outer sleeve is tight, this may be harder to slide a sleeved album back in the cover, just a matter of paying attention and it's fine.

A valid question is: why should I bother replacing the inner sleeves on my records? The most extreme example of "why?" that I have experienced: I recently found a sealed original pressing of Ozawa's "The Rite of Spring" on RCA, 1968. I paid a bit of a premium for it since it was still sealed, opened it, and found that the original RCA plastic lined inner sleeve had chemically reacted with the record surface, permanently damaging the record, which was otherwise pristine and factory fresh. One supposes that in 1968 that RCA thought this inner sleeve was a premium product, however time has proved it otherwise. I, along with many thousands of other people out there, have been using these MoFi sleeves for at least 10 years without any notable issues. Paper, and cardboard, factory-provided inner sleeves can scar, scuff, and scratch the surface of the vinyl as the record is being pulled out; note how often descriptions of used records being sold include the phrases "paper scuffs" and "hairlines" due to this fact. These MoFi sleeves are designed to minimize that sort of destruction, and as far as anybody can tell at this point, also designed to be archival and not react with the surface of the vinyl. All the new vinyl that comes through here gets a wet vacuuming with the Opera Consonance record cleaning machine, using several varieties of Audio Intelligent record cleaning fluids, and then the original inner sleeves are replaced with these. I am also slowly replacing the inner sleeves on thousands of other records with the Mobile Fidelity sleeves. I've gone through quite a number of packages of these inner sleeves over the last 10 years with no problems, other than the fact they can be a little frustrating in use, i.e. the softness and slickness of the materials used can require a bit more extra effort to separate and insert the records. The sleeves are about a dollar each after shipping, but if you're serious about preserving your vinyl, they are pretty much the best option out there. I have noticed some off-brand knockoffs out there in a lower price range, but since I have many years experience with this product, I think it's probably worth the extra money to stick with the brand name. If you're going to go through the trouble of trying to preserve your records, you may as well spend the extra money. I consider myself more of a record listener than a record collector, but I would still like to preserve these items in the best possible condition for the longest time.

Très belles pochettes doubles. La pochette de disque est vraiment protégée et mise en valeur.. dommage un peu cher .. plus de 20 euros pour 10

Love this product.

Este producto no es la opción más barata pero es la referencia del mercado. El plástico es muy suave e incluso puede que haya solucionado mi problema de estática pues antes podía escuchar y sentir una descarga eléctrica cada vez que tomaba un disco de la tornamesa, ahora esto ha desaparecido, así te ahorras el Zerostat y ese tipo de productos, aunque puede ser que también tenga que ver con por el proceso de limpieza en una máquina ultrasónica que tengo. Creo que son las dos cosas. Mi única queja es que he ordenado el producto en dos ocasiones y en las dos lo han enviado en una bolsa de plástico sin protección por lo que las fundas se pueden doblar y al ser de papel el daño es considerable. Un envío me llegó perfecto, el segundo con marcas de que se habían doblado. Podía haber regresado el producto pero al final no me pareció catastrófico y decidí conservarlas.

Produto de primeira, ótimo material e ótimo acabamento. Recomendo.

I've been using them for my inner sleeves. Nothing beats the first and original. Still planning of getting some more in the near future.
