These archival quality, acid free sleeves are made out of high density polyethylene, and provide the best possible protection against dust and scratches! They do not “sweat” like low density inner sleeves, and stand up nicely in the jacket. The round bottoms allow for easier record insertion and removal from the record jacket. Each sleeve measures 7” x 6-15/16” - the perfect fit! These cover your naked vinyl 7” record to keep them safe - perfect for collector and reseller alike! This listing is for 4000 individual sleeves.
