It’s reasonable to keep rice ball fresh to eat later at lunch which were made in the morning. It should not be rapped by laver at once but just before when you eat.
The most important to do is to avoid bacteria which would be between warm rice and laver. It might increase a lot when it would be eaten. So never rap laver as long as such hot days, otherwise it should be kept in a cooler box.

I agree .
I can eat hot rice ball at home.
When I eat it at out side It’s cool so into cooler box.
I don’t take lunch recently.
I eat out in restaurant or cafe🍝🍛🎂🍲☕
