Don’t let your banner and advertising flags blow away in the wind! Instead, take steps to ensure they are secured to the ground. The Fillable Water Ring Base is made of a durable, hard plastic and can be filled with water or sand for extra flag stability. It is recommended to be used in conjunction with our cross base with the fabric banner flags. It holds up to 1 gallon of liquid. Make sure people see your branding and messaging where you need it the most- at your retail environment, trade show booth, or other event instead of blowing by in the wind.
