Inner sleeves are protective coverings used to store vinyl records. They are typically made from paper or plastic and help prevent dust, scratches, and other damage to the record's surface. A good inner sleeve can also reduce static electricity, which can affect sound quality during playback. These sleeves come in various styles, including plain paper, anti-static, and poly-lined options. Collectors often choose high-quality inner sleeves to preserve their vinyl records and maintain their value over time. Proper storage with inner sleeves can enhance the longevity of LPs and ensure a better listening experience.
