VINYL OUTER SLEEVES: 12.79" * 12.79". We tried single LP, double LP, and gatefold vinyl jackets. They can easily slide in or out of the outer sleeves. The sleeve will extend a bit beyond the record album cover so that the edges of the cover will not be worn. You can see a little bit of space while records albums are in. But we should leave more space for old, weathered albums. Instead of sticking close to the album. | Thick & Crystal Clear: The vinyl records outer sleeves are made with 3+ mil premium quality polypropylene, thicker than standard record covers, which are designed to provide durable and high-density protection. These outer sleeves have good visual transparency and won't fog up, unlike industry sleeves. And soft material won't rip and won't scratch your vinyl covers. | ACID FREE and LONG-TERM STORAGE: ACID-free material ensures no risk of vinyl album artwork storage. You don't have to worry about the cover sticking to the sleeve. Every record deserves to be carefully protected. | Small price to pay to protect items that are irreplaceable. These records collections maybe start when you were a kid, or from your grandpa, or from your father..., or you spend 20 to 40 dollars. 0.5 dollars for each outer sleeve is great value for those valuable vinyl records. | Money-Back Guarantee - We are dedicated to your complete satisfaction. If our vinyl sleeves don't meet your expectations, simply let us know and receive a refund. Make your purchase with confidence-it's completely risk-free!
