I think that's the stuff I get from the pet shop if I run out of h4p.
It's ok stuff but usually quite brown and really soft in my experience, which some rabbits like, but mine prefer really stalky stuff (they mostly leave the soft bits of timothy & rye from h4p) so they usually end up not eating half what they normally do until the delivery comes.
personally I would rather pay the small difference for hay for pets, but I suppose it depends what your rabbits like.
