The 7.5?x 3.5?x 3.5? (approx.) Dry Box is big enough for your wallet, cell phone, camera, cigars, etc. It seals tight to keep water out (it has a rubber gasket to make it water-tight), and it holds firmly to the side of your console or other vertical surface with our powerful 4.5? SeaSucker. Two clips snap tight to keep the lid closed.
