Puck Hooks from Zone Denmark feature an advanced and adjustable suction disc that can easily bear 5 kg. Not only that, they can be mounted on cupboard doors, mirrors and other smooth surfaces without leaving any marks. Forget about power drills, hammers, nails and holes in the wall. Puck Hooks have a built-in suction disc that creates an extra-strong vacuum when you turn and adjust the button on the front. The hooks are available in two variations – Puck Hook Single and Puck Hook Double.
