The layer of material can have a mount (5460) that extends into a slot or notch (5456) in the fastener cartridge between the first connector and the second connector when the layer of material is secured to the fastener cartridge. The layer of material can be a buttress material and/or a tissue thickness compensator. Further, the layer of material can have a reinforcement feature and/or a scalloped edge around at least a portion of the perimeter thereof.
