bl1ndThese also have a textured back, although the KMCs seem to have an airier kind of feel on the backing while these ones feel a tad more dense. KMCs also poof quite a bit more than these but that should go down with repeated use. As far as durability, KMCs are much more expensive but are better quality as well. You'll be hard pressed to get a split KMC but the Ultra Pros can split fairly easily during mash shuffling. This is still a great deal though so even if you're remotely interested, I would suggest joining this drop. Very worth it imo!
bl1ndThese have a textured back as do their regular sleeves. But these also have a matte front, compared to almost all sleeves out there. Great as they don't slip when they're new but also feels less grimy after a few weeks.
