About 1 inch thick, 2 per pack, roughly 1 lb total. From the fifth rib, just before the ribeye section starts. More connective tissue than a ribeye, but great flavor when cooked right.

High heat — cast iron or grill. Medium-rare to medium works best. Don't go past medium or the connective tissue tightens. Season simply with salt and pepper.
Will last 2-3 days in the fridge when fresh or once thawed. Will last up to 6 months frozen.
