Thank you for viewing. The product is "Easy-to-install, super-strong hooks, leaving minimal marks, and replaceable, set of 2, 2 sets." Each hook can hold up to 7kg vertically, making it convenient for displaying heavy paintings, etc. I had prepared extra and stored them for a long time, but I no longer have a need for them, so I am selling them. When using the product, please be sure to read the instructions and use it responsibly to avoid accidents. I hope someone who needs them will find them. Thank you.
