can you tell me what this is called

Can anyone tell me what this chew tube thing is called or by what brand, I need to order 3 each for the bunnys but cant find it anywhere, got it from dobbies but cant find it on there site, I was hoping to find them online so can order 3 but no luck, nothing like them anywhere. charlie loved his and it lasted him ages. He needs something as good as this to keep his teeth trim with his other bits and bobs, the babys would also benifet from it.

Theyre called "Snack Shacks" They do different sizes and designs too.

PAH sell them

Thanks folks, couldnt find them online, need 3, just got a cheap chew tube (they big loo roll like things lol) gp size for the babys they be ok with them for a while yet there still really small, charlies is the full size.
