There are two different types hooks on a magnetic basis. They are directly magnetic, depending on the type of substrate. You will naturally come across magnetic hooks on a metal surface. But there is now also an indirect way possible.
Using our so-called Goodhangups Magna stickers, a selfadhesive metal plate can be applied to a flat wall (including surfaces such as concrete or stone) without nails or screws. With that, the foundation is laid for the magnet that holds the photos, poster or other images between the magnet and the sticker.
