FabeSafety D522 4+1 Pack Child Lock I am selling this because I purchased it but did not 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 an easy-to-understand diagram 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. It will be shipped 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 due to amateur home storage. 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 pack it carefully to prevent damage, wetting, or folding. I usually ship within 1-2 days, but I will ship as soon as it is ready. ※It was stored in a dark place at home, but it is amateur storage.
