Prep your soccer field for regulation games with these Markers Inc. Spring-Loaded Soccer Corner Flags. A necessary part of any finished soccer pitch, these flags are used to outline the playing area and provide a point of reference for completing corner kicks. With a highly visible design that can be easily spotted from anywhere on the field, these bright orange flags help players keep the ball in-bounds. Plus, high-intensity games won't break the durable PVC poles, since the spring-loaded mechanism is designed to keep them upright, even when hit by high-velocity balls or run into by distracted players.
