## Description

MOBILE FIDELITY SOUND LAB INNER SLEEVES

Review: A great LP liner sleeve for yoru precious records - I bought these a year ago January via desertcart 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.
Review: Protect your vinyl LP's! - What is there to say about a record sleeve? However, these are much better than the paper ones that usually come from the factory.
