If you spend a lot of time at the pool or in your own pool you will want to buy you a set of these Inflatable Duck Pool Floats made just for drinks but i will mention not limited to drinks because you can also put other small items in these such as your sunglasses, tanning oils and even your waterproof bluetooth speakers if small enough in these.
This set includes three small duckies that are so easy to blow up without wearing yourself out. Each duck held air good without leaking and chills around the pool all day long even when we are not in there.
As mentioned above you can put other items in these and keep them from falling in the water. I have used them for cups of pop, cans and bottles of water along with the lotions and our little speaker and they have held all of the items up out of the water without tipping over and sinking. Really a cool thing to have especially when you are entertaining and having pool parties. Totally worth the purchase!
