Just like the name says, this 2-cup holder also includes a dry box right in the middle of the action, giving you storage for several peoples wallets, cell phones, keys, cameras, etc… Attaches vertically only great for the side of a console, cooler, bait tank, etc… Held in place by one sturdy 4.5 SeaSucker vacuum mount, which means you can put it where you need it, when you need it.
