This stretchy string is so much fun - you can pull it, oscillate it, twirl it, fling it, shoot it into the sky--it’s just too much fun for one, and it’s stretchy enough for two. Two 12" strands come in one package and each one will stretch out to 10 feet in length. Highly recommended as a cool stocking stuffer or birthday gift!
