How to use the magnetic hooks in a proper way?

1. The attached surface should be iron with magnets adsorbing fully and directly.

2. Stainless steel or Alluminum material is not available for the magnets to attach.

3. The magnets hold more firmly on a thick iron attached surface rather than on a thin iron surface.

4. Pay attention that high temperature over 80℃ could lead to the loss of magnetic power.
