MTM CASE-GARD J-20 series ammunition cases are a favorite of rifle enthusiasts throughout the world. Made of virtually indestructible polypropylene that will not warp, crack, chip, peel, expand or contract. Fit easily into a shirt or jacket pocket during hunting and are also ideal for keeping special loads separate.
These boxes are great for storing/carrying ammo. I have used a variety of them in various colors (when available) for almost 40 yrs. They last forever; and, while some may be concerned that they open too easily spilling the contents, the situation is easily remedied. The next time you have an un-serviceable inner tube from your child's bicycle, save it and cut it up into rubber bands of various widths. They will last for years.
