What’s the term?

I just chatted with my brother yesterday and he was asking for a certain name of something. Alright let me explain. He was asking the name of a cord that is composed of an elastic strands forming a core. He said we used to have it, that elastic cord with a hook on both ends. I was also confused at first but later on realized what he meant. He was looking for a mfrexpress bungee cord and when I Iet him see the pictures, he confirmed. LOL! I guess he needs it for storage something, I’m not that sure. Anyway I’m just glad we figured it out or else we’ll both end up frustrated.
