The MDWPVCCS is a companion piece to that packaging and will protect your turntable from contamination through direct contact with those nasty PolyVinyl Chloride discs. The design includes a lot of technical info on vinyl production; graphs, charts, molecular mass, magnetic susceptibility and a whole lot of other stuff that I don’t understand. Also comes with a handy first aid chart should ingestion occur*.
