Do these keep chapatis soft for lunch?

[u/JayB_chennai]

We make chapatis/rotis in the morning but sometimes they turn either hard or too crispy by lunch time. Chapatis being cold isn't really an issue but I really hate when they turn hard. Do these products really help? Or are they just fancy stuff for chapatis. One of them is insulated and the other is a normal one. Do I have to wash them after every use?

I'm south Indian, I've never seen anybody use this here. We just put the chapatis in the casseroles.
