Twenty feet of 3 inch poly tape printed to read like a hazard barricade, which is the whole joke: cordon off the recliner, the driveway, the birthday chair. The stock is all-weather, so taping it across a garage door or a mailbox post in the rain will not turn it to pulp.
It cuts with scissors and pulls off painted walls without much argument. Sold by the package (1 streamer) or by the case (12 streamers).
