MoFi Original Master Sleeves HeavyWeight Edition (Pack of 50)
Mobile Fidelity's Original Master Record HeavyWeight Inner Sleeves are the premium choice for protecting your vinyl collection. Built with 120gsm thickness — noticeably heftier than the standard 80gsm MoFi sleeve — these three-ply, anti-static sleeves are designed for collectors who want the best possible protection for their records. Construction consists of a paper layer sandwiched between two sheets of high-density polyethylene (HDPE), with a translucent HDPE front so you can still see the record inside. The added weight and rigidity make it easy to slide LPs in and out without risking bent or creased corners, while the anti-static properties help keep dust and debris away from the vinyl surface. The heavier-gauge design also holds its shape better over time and with frequent use, making these sleeves a smart long-term investment for anyone serious about preserving their record collection. 120gsm heavyweight three-ply construction Anti-static design reduces dust and debris attraction Paper layer sandwiched between two HDPE sheets Translucent HDPE front for easy record identification Reinforced rigidity prevents corner bending during insertion Retains original shape even with frequent use Sold in packs of 50
