Used heavy duty traffic / construction cones 27" tall with reflective tape. Most are grimy but otherwise in good shape; 5 cones have damage to the cone or base (last picture) but are still functional. These cost $45 - $70 new. Yours for $15 for one cone; $65 for 5 cones; $110 for 10 cones; $200 obo for all 20 cones; Porch pickup.
