These are 50 BRAND NEW 7" 45rpm white paper inner sleeves with a hole. The paper used to make these are also certified by the Sustainable Forestry Initiative, and made with 30% post consumer waste. These sleeves are archival quality: acid free, and alkaline free! Made in the USA. The inner sleeves measure 7-1/8" x 7" (or 180.98mm x 177.8mm). The sleeves feature a 1/4" lip between the front and the back for easy machine insertion. The sleeves have square corners and are made from heavy-weight paper (20#). Replace your worn out or torn inner sleeves and freshen up your collection. These are what we use in our own retail store! (These go over the naked vinyl record and slide into a jacket or outer sleeve.) Perfect for cleaning up ones personal collection of written on, stained, and ripped up sleeves - or for replacing on vinyl you're trying to sell!
