Are these safe? (grapevine, cork, eco-earth cocofibre)

[odyssey~]

Are these safe? I see them used for hamsters natural enclosures and I wanted to try making Odyssey's place more natural.

Grapevine wood- Exo Terra Forest Branch, Small : Amazon.ca: Pet Supplies
Cork logs- Zoo Med CF9M Natural Cork Bark, Round, Medium : Amazon.ca: Pet Supplies
Eco earth coconut fibre (for dig box) Zoo Med EE24 26084 Eco Earth Loose Bag, 24 Quart : Amazon.ca: Pet Supplies

Also is children's play sand safe for a dig box? Or soil?

Thanks!

I believe grapevine is safe, Cork could possibly expand in their stomach, so I'd pass on that, and cocofibre should be fine as long as its not treated. However this is just what a quick Google search has resulted in so digression is very much advised. Personally, I would still sto stuff i know is 100% safe, but there haven't been any horrible stories about any of these. Also children's play Sand is safe, as long as there are no sharp bits

I've been told that coconut fibre can also expand in their bellies, so I've always stayed away from it.
