This is the PREMIUM, Extra Heavy Duty version of our standard 3mil thick sleeves that have been an industry favorite for decades! Square Deal Recordings & Supplies (established 1972) has been making the 3mil version of sleeves, our own custom creation, for over 30 years. Around a decade or so ago, due to customer demand - we started making this EXTRA HEAVY DUTY 4mil version - and customers love it!
These are 12" 4 mil outer sleeves. These are extra heavy duty sleeves, but are still very clear! They're perfect for protecting your precious vinyl! The sleeves measure 12.5" by 12.75" (or 323.85mm x 317.5mm) and are flush cut at the top (do not have a flap to keep them closed).
These sleeves will accommodate single records AND double gatefold records!
We use virgin 1st quality polyethylene on all our sleeves.
