FabeSafety D522 4+1 Pack Child Lock I am selling this because I bought it but didn't use it. This is a child lock for drawers to prevent children from playing with them. The handle is magnetic. It may not be usable depending on the shape of the door. The instructions are not in Japanese, so I have included easy-to-understand diagrams in the 11th photo. Compatible thickness: 2.5 cm It depends on your environment, but it worked on my doors, which are 3 cm thick. I plan to ship via Yu-Packet Post. Please consider the box as cushioning material. Please cooperate with simple packaging. Please refrain from purchasing if you are looking for perfection or are overly concerned about details. ***Please note*** Although it is unused, it is a used item that has been in someone's hands once. I have noted any issues I have noticed, but please forgive any oversights as it is stored at home by a non-professional. Please note that there is no warranty for the deterioration of all items over time. Please understand and agree to the above notes, and consider carefully before purchasing. *After purchase* I will carefully pack the item to prevent damage, wetting, or folding. I usually ship within 1-2 days, but I will ship as soon as it is ready. *I have stored it in a dark place at home, but it is stored by a non-professional.
