I have a problem when it comes to zip ties, all of the ties I use are really long or really small. The small ones get lost in a pocket and the big ones fall out if stood into a pocket.
So I use a zip tie as a dispenser.
Step 1: Set Up
Make sure that the textured track is facing upwards.
Now slide your stock of zip ties onto the locked on pointing down, this way they don't lock and will slide off easily.
This works for all zip ties and you can add as many sizes as you need and when you are done cut the locked tie off. All it cost was one zip tie from the pack. Easy!
