All your zip ties, your way. Magnetically held on the back or bottom. From 4 to 18". Small and larger bin sizes for the sizes you use the most of and just a little of the ones you don't use so much. If you run 4, 10s, 18s or just 6s. you can combine to make the storage how you need it.
The large bins have dividers in them to keep the zip ties from curling and disappearing into the bottom.
