Your vinyl records are a valuable investment. Let's keep it that way! Your record collection is more than just music...it's a tangible archive of moments, sonic journeys and personal legacy. That's why at Groove Guardian we designed our Black Poly-Lined Paper Inner Sleeves to deliver the premium protection your 12″ LPs deserve. Whereas standard paper sleeves leave your records vulnerable to dust, static and micro-scratches, our hybrid construction uses a smooth poly-ethylene lining inside a dense black paper shell to combine the best of both worlds. The outer is stiff enough to maintain shape and support, the inner liner ensures a smooth, frictionless handling and zero static. Each sleeve is acid-free and archival safe...so whether you're storing, spinning, or displaying, your vinyl is shielded from the elements that degrade sound and value over time. Whether you're a DJ rotating through heavy use, a collector preserving rare pressings, or simply someone who loves how vinyl feels and sounds, our sleeves deliver. Fit your records with confidence, spin them in peace, store them with pride.
