There are many ways to use a flexible magnet. To illustrate their applicability, here are a few examples:
Flexible magnetic sheets can be made into colourful fridge magnets. Flexible magnets are particularly suited to this role as they can be cut into any shape (for example, a puzzle shape as a game for children).
Flexible magnets are used to create signs for a variety of different applications, most commonly, car magnets, where they can be used for mobile advertising.
Flexible warehouse magnets are used for signs which can be easily changed and replaced due to a high stock turnover.
The very nature of a flexible warehouse magnet aids in this role as it can be peeled off and reattached onto any ferromagnetic material, such as a steel shelf, an infinite number of times.
Most also have a replaceable piece of card which can be easily written upon and replaced when they are no longer needed.
