The Roto Grip MVP+ Accessory Case was built to meet the storage needs of the serious bowler. Multiple zippered pockets and mesh pockets for storage. As well as a foam insert to securely hold interchangeable thumbs and tools. And what makes the Roto Grip MVP+ Accessory Case even more awesome, is that it fits comfortably in the main compartment of the Roto Grip MVP+ Backpack. It’s ok, you can thank us later.
