"Dual purpose. Only product that really works for screws of all size."
These are really a great deal due to the fact that they serve two purposes. They are perfect for storing screws and for racking them. They keep the screws from shredding your pants. I use them to store my BD Express screws, and they work great. There is a lip at the bottom to protect the spikes. The 22 cm stick out of the top a little, while the 10 and 13 cm screws are still held in fine thanks to the rubber guards.
