The No-Lose™ Call Case protects and prolongs the life of your turkey, elk, and predator mouth calls. It is designed to breathe, allowing your calls to dry out properly. The No-Lose™ Call Case has a spring hinge that opens quietly and closes automatically – very important when you are in the woods! It fits right in your shirt pocket. Your calls will stand upright, not on top of each other, so you choose the one you want.
