No matter how clean the refrigerator is, sometimes it just smells. Getting rid of the smell can be a challenge, but if you have an odor absorber handy, that foul smell can be but a memory. These come in four assorted colors. Simply remove the plastic wrap and place in the refrigerator or freezer. Shake once a month to keep it fresh. Good for 3 years in wrap or 6 months after it's been opened. Each measures 5" x 2 1/2".
