We double check incoming vinyl supply, visually to make sure that there are no damages/dings/bended sleeves/seam splits etc. before we list them. We use 3,5 mm thick corrugated cardboard vinyl mailers in which we ship up to 5 x 7", 10" and 12" vinyl formats and for more than 3-5 LP's we use Four Lax vinyl mailers, reinforced with cardboard stiffeners(if needed). For larger orders or box sets we use 3.5 mm up to 5 mm thick cardboard boxes reinforced with cardboard/thick paper/bubble wrap etc. Factory sealed items will be shipped as they are but per request we can remove the shrink wrap and ship the vinyl record(s) outside the sleeve to avoid possible seam splits. Vinyl that have been released in a resealable plastic bag, will be shipped outside the sleeve to avoid any damages/seam splits during transit.
