Items made from card/cardboard are throw away items, so if they get urine soaked, they can be replaced. Wooden items do tend to retain urine which is why many of us don`t tend to use wooden accessories. Small wooden chew sticks are fine, but I find mice don`t bother with them to be honest.
Things like toilet roll tubes, tea boxes, tissue boxes are all good choices and the mice can play in these aswell! Add in some toilet paper strips for the mice to play with and some shredded newspaper (using a shredder).
If they have hay, they will nibble that, but not all mice do. I don`t tend to use hay or straw due to parasitic issues and don`t want to risk giving my mice skin issues if the grasses are harbouring these tiny nasties. Freezing the hay is said to kill them off, but I don`t trust it.
You can even buy those straw nest balls and tunnels, but these too might get stinky after a while, so stick to cardboard items that are small and easily replaced.
