Adhesive door lock that can be easily installed without drilling, perfect for pet and child safety. Purchased on Amazon. I bought multiple, and I am selling this one because I don't plan to use it. It seems to be for preventing babies from opening refrigerators and cupboards on their own, but in my house, I bought it to install on the refrigerator that stores rice, which is located outdoors. It is new and unopened, but please refrain from purchasing if you are concerned about home storage. Feel free to ask any questions. I will use recycled packaging materials.
