Translucent rubber/neoprene cord

Hello everyone! I saw something at a show this weekend that I have
to find a source for. A customer of mine was wearing a necklace
that she said came from Australia. Among other things, it was made
from a bright orange, translucent, rubber cord with a square
profile. She thought it was neoprene but was not sure. It looked
similar to the rubber that Technomarine uses for its watchbands.
Does anyone know what it is and where I can get some?

Thanks!
