This Hard Shell container will keep your delicate items safe. The foam inners provide a flexible space that will cup and hold anything within the dimensions of the box. We've been using it to transport our Apple Mouse around and it's a perfect fit. The box stays closed once you've put all of the clasps down. The clasps give a satisfying snap when you've clicked them into place. Once they are down there is literally no way it's coming accidentally undone. The box is super sturdy and waterproof. You could sit on it without breaking - you wouldn't want to stand on it though. After using it for 6 months the clasps have started to come apart - consider that we are opening and closing 3 times a day.
