The issue is really how tight are the shrinkwraps.The warpage is caused by overshrinking.This is a prolem I have encountered on several new releases lately.Unsealing would absolutely impact resale value in a negative fashion.Who would believe "opened but never played"? Maybe the same people who believe used cartridges have "low hours".
Leave Wrapped or UnWrap?
Recently I have purchased several extra copies of my favorite records. Perhaps I will actually use them one day or maybe sell them off down the road. For example, I have an extra copy of The Beatles, 'Love' album. Question is: should I leave these records sealed or go ahead and open them? Will leaving them sealed for years cause them to warp?
