Our case is designed to fit in the corners of your gear bag.   It will hold every barrel we have tried so far up to 16" in length.   We designed our case with a fold-able flap in the center which allows you to hold a combination of (x10) backs and fronts without the risk of them hitting each other.   Or you can leave the flap down and hold (x5) 1-piece barrels.
