Yea @blackminirex they are in a hard stack, I just watched a YouTube video on them, you can break them open and they can expand into a lot of hay. I'm thinking it might be better for my allergies (in allergic to Timothy hay). https://youtu.be/xAhU6xmqPAo
I have used them and while they say they're less dusty I find they're more messy than the loose oxbow hay because the strands of hay are shorter. Even though I twist them open, the rabbits will grab chunks and take them to the middle of their rug and throw them all over vs. the loose hay stays in the litterbox.
I do keep them in my earthquake kit for emergencies though!
