Steve looks back down into the box, grabs several lengths of white rope, letting one run through his hand thoughtfully, the fibers tickling his palm. But Adam's in a rare mood; rope won't be enough. He sticks his hand back in, comes back up with a blindfold, and gathers everything to his chest, pushing the box back into the closet.
The rope's for shibari, the only thing Steve can do; he's good with knots, and the whole emphasis with shibari is on the tied-up person's pleasure, which is what he wants to give Adam. He doesn't want to tie Adam up and make him hurt, or suspend him for hours, or anything so extreme.
