I was going to pick up a small bag of aspen to try it out. The small bag was $7 and the larger bag was $13. Then I saw someone selling this huge bag and figured it would be around $50. Turns out it was $20 so I picked one up. I hope it's the same stuff. The bag says:

Aspen Shavings - Kiln Dried Hardwood Bedding

Autoclavable, Laboratory Grade, 100% Virgin Wood Fiber

Volume 9.0 cu ft, compressed to 3.0 cu ft.

Does this look like the right stuff for BP's?
