You can wrap up and cover that food of yours with this handy-dandy plastic wrap. With it being clear, you can see exactly what's wrapped up in your fridge without having to unwrap it first. And I can't forget about how nice the slider is, you don't have to try cutting the plastic with scissors and risk the plastic clinging to everything. Just pull out the amount you want to use and slide the slider arcross the box, nice clean cut.
