The bestseller among the self-adhesive magnetic tapes
This 20 mm wide self-adhesive magnetic tape is made to attach non-magnetic objects to metal surfaces. 

This magnetic tape is available in lengths of 1 m, 5 m, 10 m, 30 m, and 50 m. It consists of strontium ferrite and flexible plastic. On one side it is coated with an 3M adhesive. The adhesive force is 98 - 102 g/cm² . The longer the magnetic tape the higher the adhesive force. For heavy objects, we recommend a large enough magnetic tape. 

Please note!
Magnets should not be placed on self-adhesive magnetic tapes, because they would demagnetise the tapes. Suitable surfaces for magnets are self-adhesive metal tapes or metal strips, for example.
