This is a special design for easy removal of the magnet patch.
The removal steps are as follows:
1. Lift the lower edge of the magnet patch to expose the black adhesive.
2. Hold the magnet patch with one hand to prevent it from springing back and
hurting your hand. With the other hand, pull the black adhesive horizontally
to completely remove it, and the magnet patch can then be taken down
without leaving any residue.
Remember that after removal the magnet patch can't be reused due to the loss of adhesive effectiveness.
