These magnetic buttons may be labeled for the 'fridge' but don't be misled ... they are great for sticking to almost any metal surface! Perfect for advertising your brand on refrigerators around town or for laughs and conversation starters at home, on school lockers, or randomly around the office. We combine heavyweight 32 lb. paper with our scratch-resistant, UV-protectant finish, excellent coloring, and a strong magnet to produce the highest quality button magnet. Square and rectangle will hold approximately 5-8 sheets of standard paper vertically while round will hold 1-2 sheets.
