The Element-Proof Field/Ammo Box Compact is a longstanding favorite in the Plano line of ammo boxes, designed to hold up to 4 boxes of shot shells. It features a water-resistant O-ring seal and the tried-and-true brass-bailed latch for an extra secure close that keeps out water and dust. But don't think of it as just a shot shell box; this general storage box can hold anything you want from tools to rangefinders.
