This is the neat way to carry tools and small parts! Made of cordura nylon, it has a zippered pouch on one side large enough to hold 16 boxed spark plugs. Then the rest has a series of sewn slots to keep tools organized and separated. A flap is then folded down to hold the tools in, and the whole thing is rolled up and secured by a heavy strap with generous velcro. We think this item is a must. Makes a great gift.
