Not invincible but good value
Color: 5pack, Size: Large
Great value for the money. We have 3 dogs and they are pretty strong chewers. They lasted a few months but ultimately succumbed to their inevitable doom. They arrived well packaged and with no unusual odors.

Actually indestructible!
Style: Two pack
I am always leery of items marked indestructible because my 100+ lb. dog chews through anything I buy him. But not this. It's solid plastic that he LOVES to chew on. And I love that there are 2 of them so he can have them in alternative places to play with. The shape and texture seems to entice him and keep him occupied for a few minutes, which is a blessing!
