Clear double-sided nano gel tape, 3 m long, 30 mm wide and 2 mm thick. It mounts light things on smooth surfaces such as glass, tile, marble, metal and finished wood, with no nails, screws or drilling. When the hold gets weak, rinse it in water, let it dry and use it again.
Before you trust it, know its limits. It holds best on smooth, clean surfaces and is weakest on rough, painted or textured walls. Use several small pieces spread across the back of an item rather than one strip in the middle, and test it for a few days before you hang anything that would break if it fell.
