3M Command - picture hook in metal - with mounting strips - 3,6kg max.

Take the fuss out of hanging wire suspended frames with Command™ Wire Backed Picture Hangers.
Ideal for use instead of a nail or hook. The hangers hold strongly to a variety of surfaces including solid, hollow and painted walls.
If you need a change, the hangers can be easily removed without damaging the surface underneath – no cracks, holes, damaged plaster, sticky residue or stains.
Replacement adhesive strips are available, so you can use your Command™ Picture Hangers again and again.
