Twisties stretch to about a foot, and stretching out the brand new silicone will change the properties in a way that makes it more flexible...more stretchy... and makes it a "natural adhesive" of sorts - you can feel it gripping the cable as you wrap TwistieMag around it - and the magnets hold tight!
DON'T WORRY! You'd have a hard time breaking them as they're manufactured with our proprietary blend super-strong and super-stretchy silicone.
It's easy! Grab a Twistie by the magnets and gently stretch it out to about 12 inches - you will feel the silicone relax as you stretch it...
This makes it possible - and awesome - to use TwistieMag not only with smaller earphone cords, USB, and phone cords but with larger guitar and instrument cables, extension cords, and bundles of cords - great for keeping yourself organized when traveling.
