The ultra-sleek design will allow you to easily glide an LP into the tightest fitting jackets. These are identical to the original inner sleeves that came with japanese pressings during the 1980's, completely static free & non-abrasive. Inner sleeves are, over the years, liable to tear or accumulate dust on the inner surfaces and this could result in scratches on your valuable records. These sleeves are treated by a special static prevention process to eliminate static electricity. Quite simply, the ultimate record sleeve. Each pack contains 50 sheets.
