Using these stretchy strings is super easy. Just grab a string and start stretching, pulling, and shaping it with your hands. You can twist it into different shapes or use it to keep your hands busy when you're feeling restless. For safety, make sure children under 3 don't use these strings as they could be a choking hazard. When you're done playing with the strings, store them in a cool, dry place. If they get dirty, you can gently wipe them with a damp cloth. But don't soak them in water as it might affect their stretchy quality.
