Always impressed by Amazon Packaging of LP's.
I save the boxes in case I get back to selling individual LPs, and someone pays a lot of money for one.
I have bought 180 gm, half-speed masters, 45 rpms. I have received 'not so special' frequently and slight warps as well, I'm only buying 'normal' new and used LP's, and because I inherited so many, I shouldn't buy any, unless, hopping around YouTube I come across someone outstanding.
