A fillable base is the most versatile option, as they are light to carry without water in, weigh up to 20kg full (with water or water, sand mix), and can also be used indoors or outside. Please note: We do not recommend storing or transporting water-filled bases as they are not fitted with water seals and are prone to leak. They are absolutely fine, however, when used outside premises. We recommend emptying water-filled bases used at shows and events at the end when you are packing up.
