jump rope:

It's better than a bungee cord or a rope for dozens of uses in home, garden, and garage
It can organize tools, lash trunk lids, attach bikes to bike racks, and bundle hoses for storage
The grip twist pairs a carbon steel alloy core with a high density foam coating for a product that can hold up to 200kg. simple, secure, and strong, it won't scratch or snap back like a bungee cord or tangle like a rope.
