The big daddies of Sports Marker Cones, these are tall, colourful, easy-to-see rigid plastic target cones.
Four side support holes which will hold a pole horizontally, a top hole which supports a pole vertically, and a grooved top which will hold a flat hoop vertically, too.
Two cones, one pole, and you've got a hurdle. One cone, one hoop placed in the top groove, and you've got a very useful target. Mix with flat round or hexagonal hoops, poles and clips.
50 cm height.
