The perfect bungee 24-inch bungee cord is made of a special polyurethane formula (no rubber/no latex) that's built to last. It won't crack, break, split, become brittle or scuff, and can withstand exposure to salt water, oil, ozone, and many common household chemicals. The super-strong, flexible polyurethane material allows for a safe stretch up to twice its original length and features excellent memory retention. The perfect bungee won't wear out or lose its shape. It is non-load bearing, but still no wuss and can be used in an endless variety of applications. It is available in several lengths and colors. Nylon ends won't scratch or gouge. The perfect bungee cord is proudly manufactured in the USA.
