People usually give me all kinds of things when they turn in their turtles and tortoises to me, and this is something that was given to me with some box turtles. I don't let any of that "junk" go to waste, and always use it on my many turtles and tortoises. I know that it says it's for tortoises, but my box turtles really like it. Would I ever buy it on my own? No, but when it's given free, yes, I'll use it up.
When I have what I consider manufactured junk food for turtles and tortoises, I mix it in with the animals' regular, healthy diet.
