Is this pet safe string safe for my rabbit?

I want to start making my own rabbit toys and I was wondering if this string is fine.

After I posted this thread I found out how much shipping was....too expensive. I'm trying to find some from another website. Do you know of anywhere I could find pet safe string at a pet store?
