With our handy inflatable drink holders, you're in one store. With our quick valves, inflating and emptying the whale floats is 5 times faster, saving you time and effort. The coaster is fantastic in the hot tub or by the lake. Ideal if you're swimming in the river or the sea. There's no worry about them tipping over, because with our 3-inch total depth and great buoyancy, they're not ascending or collapsing. Most pool drink holders are 0.2mm thick, but we've designed them with 0.6mm material, which is three times thicker and more durable.
