I've used magnets to stick things to my walls and ceiling (don't ask) and this gets the process done speed up a lot. This is a low gauss, single-sided adhesive, flexible magnetic sheet suitable for attaching light-weight ferromagnetic metals. Craft project class, I doubt they will hold anything over a few ounces but it depends on the surface, orientation and angle. The adhesive is weak, even if the magnet is holding a heavier flat object, the adhesive is unlikely to hold something too heavy without additional fasteners. Ideal for a sewing or craft table to create a "magnet point for metal pins and lines".
