Mobile Fidelity Sound Lab Original Master Inner Sleeves 50pk

Mobile Fidelity Sound Lab Original Master Record Inner Sleeves are three-ply, anti-static sleeves designed to protect vinyl from dust, static and surface wear while fitting most standard LP jackets.

These inner sleeves are the same high-quality inserts Mobile Fidelity Sound Lab has used in its LP packaging for decades. Built with a three-ply construction and an anti-static finish, they are engineered to reduce surface noise and hold records securely inside jackets. Collectors, reviewers and labels have relied on these sleeves for dependable preservation and everyday handling protection.

How do these sleeves reduce static and surface noise?

The sleeves are manufactured with a layered design that minimizes friction and static build-up when a record is removed or replaced. Less static helps reduce crackle and pop caused by charge attraction, improving playback cleanliness without altering sound.

• Three-ply construction lowers friction and wear on grooves
• Anti-static treatment reduces electrostatic charge buildup
• Snug fit limits movement that can create surface noise

Will they fit all of my LPs and special pressings?

These sleeves are sized for standard 12-inch LP jackets and accommodate most contemporary and vintage pressings. While they suit the vast majority of records, some thick or irregular deluxe sleeves, heavy-weight vinyl with large center labels, or certain gatefolds may require a slightly different fit.

• Designed for standard 12" LPs and common jacket dimensions
• Works with typical single and double-pocket jackets
• Check size compatibility for unusually thick sleeves or specialty pressings

How do these compare to basic paper or polyethylene inner sleeves?

Compared with single-layer paper or plain polyethylene sleeves, Mobile Fidelity's three-ply inner sleeves combine protective cushioning with anti-static performance. They are intended to be more durable and less prone to trapping dust, offering a higher standard of archival care without the stiffness of some thicker archival products.

• More durable than single-ply paper; less abrasive than some plastics
• Anti-static layer reduces attraction of dust and particles
• Long-standing industry use indicates trusted performance

How should I use and store records with these sleeves?

Slide the record gently into the sleeve with label side facing out to avoid scuffs along the rim. Store jacketed records vertically, in a cool, dry place away from direct sunlight and extreme humidity to extend both sleeve and vinyl longevity.

• Insert records carefully to avoid edge wear
• Store vertically to prevent warping and pressure marks
• Avoid high heat and moisture to preserve sleeve integrity

Who is this for: Collectors, audiophiles, record store owners, archivists and anyone who wants reliable protection for LP collections will appreciate these original Mobile Fidelity inner sleeves. They suit everyday handling, resale preparation, archival storage and any situation where reducing dust, static and surface wear matters to preserving playback quality.
