According to the description they can be placed in the fridge. But how to use them when they need to be applied cold to the face. Well I didn't read the product description very well because I put them in the freezer and they broke. The box says China so I couldn't read a word of it. So I can't tell you if they work. . Because I've never tried them. But I tell you that I will not buy this item again. I don't want to give stars but they won't let you.
