Flexible magnetic labels will cling to the outside of servers having metal shells (e.g, stainless steel). They will not cling to plastic, or to metalic-coated plastic.
Labels are useful for identifying the contents of the server when you have multiple servers in service. 23 different labels say: Milk, 2% Milk, Skim Milk, Half & Half, Cream, Hot Water, Tea, Ice Tea, Coffee, Decaf, Regular, Breakfast Blend, Columbian, French Roast, Gourmet Blend, House Blend, Almond, Amaretto, French Vanilla, Hazelnut, Irish Cream, Mocha, and a blank one to write your own with a marker.
Magnetic labels are 1.25" High, and 3.5" Long. Any specific label (e.g., "Coffee") is sold as a set of 6. Choose the label you want when ordering.
