Photo is just for size comparison. It’s really hard and not chewable but he’s already put a dent into it, as you can see. Not sticky, smells right out of the packaging !! We loved that! Its size is about a 20 oz Powerdrink but it’s sturdy and heavy. It’s going to last us such a long time . The only thing is the logo might be worn off sometime soon. Go birds! 🦅
