Vinyl Music Madness parcels are packed carefully so that records don't get crushed or damaged in transit and there should be little/no room to move.
With the exception of sealed items, records are always removed from their outer sleeves to protect them from seam splits. All records are packed in a high quality record mailer with two cardboard stiffeners. We never use jiffy bags or low quality mailers for LPs. UK parcels valued over £20 and those sent to non-EU countries are sent in oversized heavy duty mailers with extended edges to give them extra protection.
