  • Holding specific umbrella in place!

  • Perfect to hold umbrellas.
Style: Square Base
We’ve had these for about a year and they helped keep our large umbrella stable without concerns of blowing over. Super easy to use you just need to buy sand or water to put into the basis. The quality is perfect. It looks this exact same as the day we got it. The weight can be heavy enough, so you feel confident that your umbrella is not gonna blow away. And fits around the umbrella that we bought off Amazon perfectly. ... show more

Filled with water placed it around the umbrella base and it works like a charm. The umbrella has been steady and it looks nice, too. Easy to move as well. Very sturdy and withstands many high winds!
