The bottom halves of quart-sized plastic oil cans are just the right shape to fit into the large nail pouches on my toolbelt. After cutting the containers in half, I swab out the oily residue with a rag (good for wiping down stationary power tools) and fill them with different kinds of nails. I keep a variety on the job, making it easy to change nails without having to dump the old ones in a grab bag somewhere.
