Get yourself a 20-oz Pepsi bottle. They're clear.
Painstakingly remove the label.
remove the little blue seal inside the cap, and drill yourself a 5/16 or 3/8-inch hole in the center of the cap.
Fill the bottle with zip-ties, putting the locking ends at the bottom of the bottle. Don't pack them in, just make it reasonably full.
Put the cap back on.
You now have a neatly storable zip-tie storage container, and when you tip the bottle upside down, the ties self-feed through the hole, thanks to the funnel shape of the bottle. Two or three tails come through the hole, requiring you to actively pull the zip tie out of the hole, so you don't end up spilling ties if you tip the container over.
