The Audio Anatomy Vinyl-Inner Sleeves are an indispensable accessory for any vinyl collector. Made in Germany, the interior consists of an antistatic foil lining (low density polyethylene) and the exterior is of paper. The paper has a die-cut center hole on both sides and corresponds to the universal size of the 12″ record. The Audio Anatomy Vinyl-Inner Sleeves provide easy and efficient protection against dust, fingerprints and moisture, resulting in improved sound quality and increased longevity of your vinyl records. To keep your vinyl records clean, we recommend cleaning them regularly with Audio Anatomy Cleaning Brushes and Audio Anatomy Cleaning Cloths.
