No hole, No adhesive. Sometimes we need an extra hook to hold our towels or clothes in a bathroom, but we (or maybe the owner) don't want any extra holes or adhesive in the our lovely house. This innovation hook will be very helpful. It attached on one of a door hinge, no holes, no adhesive. To install it, only need to pop out the pin of a door hinge a little (1" more or less) to put on this hook and then push the pin back. And also it is very easy to uninstall in the same way. It is not only perfect for permanent use at home and also very good for use in travel. It would not damage anything in the house while install and uninstall.
