Chunk has 3 different kinds of the "indestructible" nylabones ... they are all still in one piece after well over a year and a half!!! LOVE IT! So worth the money they cost. He's a crazy chewer too.

@loonatic8 - I'd be happy to pick some up and send them to you if you can't find a place that ships them to you. But you are right - it will still probably be quite expensive.
