A Fetch it case is a convenient way to always have your dog’s favorite ball ready for action. After playing simply snap it over that slobbery tennis ball and keep your hands clean. Strong magnets hold the case together. Twist the top and bottom cases to open when it’s time to play fetch again! The carrying case attaches to an aluminum carabiner clip by a durable cord loop. You can hang the Fetch it from your backpack or your dog’s leash. Each Fetch it case comes with a bright yellow no-squeak tennis ball inside.
