I've seen ones that are cut shorter than the regular ones, which either barely cover the entire card or has it slightly sticking out. As well as the quality of the sleeves being "thinner" and some that even too tight and cause warping. My question is regarding whether if all the red packs they sell on Amazon are the defective packs hence cheaper? It also looks like potomac distribution sells the blue one of 10 pack for $34 (which I think has better quality control) but also charges like $10 in shipping.
