stretch elastic cord (Pt Richmond)

Hello, since a lot of things are in boxes, I don't know where to find my elastic stretch magic cord to make a necklace and bracelet for a little 2 yr old neighbor. It looks like pics I've attached.... not too picky. Anyone have any that you don't want anymore? I'm just asking people in Pt Richmond for this, because it's definitely not something I want to use gas on... hopefully, I can simply walk over and pick some up. Thanks!
