I'm selling these because I bought them in bulk and have some left over that I haven't used. These are child locks for doorknobs that I purchased online. I've been using the same type for 4-5 years, and the adhesive tape hasn't peeled off. They prevent babies and children from opening doorknobs on their own. Since they might barely fit in a post, the packaging will be simple. Please understand this before purchasing. (If you want bubble wrap, please comment. The shipping cost will likely be added.) If you have any questions, please feel free to ask. Compact hinge-type door locks to protect your door's safety, with 3M PE foam adhesive tape. - Color: White - Adhesive Type: 3M PE Foam - Design: Hinge mechanism for door security - Size: Compact design Thank you for looking.
