Your 45 rpm record collection deserves the very best in protection. Our 7" die-cut white jackets are made from the highest quality 15 pt. high-gloss white cardboard exclusively for Sleeve City. The protective finish is designed to repel household pollutants, grime, fingerprints and mildew, and the cardboard is thicker and stronger than competing jackets. Includes a convenient thumb notch for easy removal of the inner sleeve and record.
