52x74mm -160 pack, Thin Sleeves (SWN-016)

I didnt expect these to be be as thin as they were, basically penny sleeves thickness. But my main concern is the inconsistent sizes. I bought 4 packs. I had little issue with the first pack, but the 2nd pack didn't fit the same cards I sleeved with the first pack(too narrow). So I switched to the 3rd pack and it was somewhere between the two. I had to really squeeze the cards in.
