Ceiling Magnets with Hook
Colorful Plastic Pot Magnets with Hook /Circular Pot Magnets
with Hook in red, green, yellow, black and other colors with an
open hook for applications such as publicity, warehouses,
supermarkets, etc.
The hooks are strong and great for hanging something on a
refrigerator. However, they can scratch fridge's paint if you move
it a bit (and that can happen any time you use it). A piece of a
soft cloth for the backing could solve that problem, so I will add
it myself. I am not reducing my rating of the product for that
because it looks like attaching the hooks to the fridge is not
their intended use but rather is a bonus.
