I'm selling these because I bought them in bulk but didn't end up using them. 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 it might be just barely able to be sent via post, the packaging will be simple. Please understand. (If you want bubble wrap, please comment. The shipping cost will likely be added.) I have two, so I can sell them for 500 yen if you buy them together. Please feel free to ask if you have any questions(^^) Compact hinge-type door locks to protect door safety, with 3M PE foam adhesive tape. - Color: White - Adhesive Type: 3M PE Foam - Design: Hinge mechanism for door security - Quantity: 2 pieces - Size: Compact design Thank you for looking.
