Description Nagaoka JC20EP is a set of 20 premium outer protective sleeves designed specifically for 7-inch EP (Extended Play) vinyl record jackets. Manufactured in Japan, these sleeves are engineered by Nagaoka—a brand globally recognized for high-fidelity audio accessories and phono cartridges — to provide archival-grade protection for your record collection. These sleeves feature an increased thickness of 100μ (microns), roughly 4 mil, which is significantly thicker than standard 75μ sleeves. This extra thickness provides a robust barrier against dust, moisture, and physical scratches for delicate paper jackets. Made from high-quality Polypropylene (PP), these covers are crystal clear, allowing the original album artwork to remain fully visible without the cloudiness associated with some polyethylene materials. Specifications Material: Transparent Polypropylene (PP). Dimensions: 190mm x 190mm (Width x Height). Thickness: 100μ (microns). Quantity: 20 pieces per pack. Compatibility: Designed for standard 7-inch (17cm) EP record jackets.
