KMC Perfect HARD: 50 Ct

These have a stiffer feel than the soft penny sleeves I used before, and the 0.10mm thickness really does keep the corners from bending. I double sleeved a whole commander deck and they still fit in my box fine.

Slid a foil rare into one of these and it felt way sturdier than the flimsier sleeves I'd been using. The 50-count pack covered most of my binder, and none of them split when I double-sleeved.

The 0.10mm thickness really does make these feel more substantial than standard penny sleeves—shuffling my deck feels much more controlled. The pack gave me exactly 50, so I could sleeve a full deck plus a few spares without any tight fits or splitting at the corners.
