The Champion Sports Universal Spring Loaded Corner Flag Set offers a versatile solution for marking boundaries in any soccer environment, be it indoors or outdoors. Standing tall at 60-inches with sturdy red flags, these corner flags boast a unique hollow base designed to be filled with sand. This feature provides additional stability on surfaces like turf or gymnasium floors, where traditional ground spikes might not be suitable. An additional safety benefit comes from the spring-loaded base that bends upon impact, minimizing injuries during collisions. This set is perfect for marking corners of the playing area or setting up drills during practice, making it a valuable tool for any soccer team or gym class.
